However, certain applications may avoid CDPRs due to drawbacks such as potential cable collisions. To improve the usability of CDPRs, the fixed frame anchors can be mounted on reconfiguration axes. This results in more complex kinematics that are challenging to control. This paper introduces a gradient descent approximation technique for reconfigurable CDPRs (RCDPRs) to identify, with low computational effort, appropriate configurations for a given platform pose to achieve a larger workspace. A workspace study shows a wrench-feasible workspace enlargement up to 28{\%} when using this reconfiguration technique on an RCDPR compared to a common CDPR.}, address = {Cham}, author = {Clar, Johannes and Trautwein, Felix and Reichenbach, Thomas and Verl, Alexander and Neubauer, Michael}, booktitle = {Advances in Robot Kinematics 2024}, editor = {Lenar{\v{c}}i{\v{c}}, Jadran and Husty, Manfred}, isbn = {978-3-031-64057-5}, pages = {149--156}, publisher = {Springer Nature Switzerland}, title = {Actuated In-Operation-Reconfiguration of a Cable-Driven Parallel Robot with a Gradient Descent Approximation Technique}, year = 2024 }

To address the organizational and technological challenges under uncertain production conditions, this paper proposes a holistic framework for production planning. It consists of a software-oriented planning architecture and an iterative planning behavior that enables continuous adjustments based on the current state of the production system and products. Principles of organizational, multi-stage production planning and technological, zero-defect manufacturing are considered in combination. Necessary engineering services can be extended by automatically integrating self-describing software services into production system-wide engineering control loops. In a first implementation step, general functionality can be demonstrated by continuous production plan and process-program generation and adaptation with simulative validation for individually configurable products based on the production system state and target goals.

  @article{Elser2024, abstract = {Computerized numerical controls (CNCs) have been invented for the automation of industrial processes. They are used, when the process to be automated is required to be exact and fast with repeatable quality. Originally, the use of CNCs was primarily focused on milling and drilling processes. Today, CNCs are utilized in a wide range of industrial processes due to the growing importance of automation. However, the integration of process information or adaptation to the needs of these processes to achieve advanced manufacturing with CNCs is difficult: Industrial CNCs are rather closed real-time machining systems. Today, process integration is possible, when the interaction between the process and the machine is decoupled in view of the bandwidth of machine dynamics and process dynamics. There are interfaces that allow for process-motivated control loops that are realized on top of the machine control loop (e.g. chatter control). Then, machine-integrated real-time control is not the focus. Besides, it is often possible to change desired values inside the control loop (position, velocity, acceleration) on an axes basis. In this case, adaptation to the process can be realized in each computation cycle. However, process dynamics and machine axes dynamics are generally treated separately. The same holds for extra actuators (e.g., in the spindle) for position control. This paper has two goals. First, it wants to create an understanding for different levels of process-machine coupling. Second, the problem of direct coupling of process dynamics and machine dynamics is focused. Machining systems design propositions as well as some examples for the coupling of process and machine dynamics in the CNC are given.}, author = {Elser, Anja and Lechler, Armin and Verl, Alexander}, day = 01, doi = {10.1007/s00170-024-14437-3}, issn = {1433-3015}, journal = {The International Journal of Advanced Manufacturing Technology}, month = {11}, number = 3, pages = {1291--1301}, title = {Process-integrated computerized numerical control: an analysis on process-machine coupling and feed scheduling}, url = {https://doi.org/10.1007/s00170-024-14437-3}, volume = 135, year = 2024 }

  @inproceedings{10590860, abstract = {Rack-and-pinion drives are preferred feed drives for long travel distances and heavy loads in large machine tools. One of the advantages compared to other feed drive systems is consistent stiffness regardless of travel length. A primary challenge with rack-and-pinion drives is the achievable accu-racy due to backlash. To compensate for backlash, electrically preloaded systems are commonly used in machine tools. In the case of electrical preload between two motors, the system is more complex to identify because the feed drive specific properties cannot be directly assigned to the respective drive train. To address this issue, this paper presents a novel method for modeling and identifying the load-dependent stiffness and damping of an electrically preloaded system. For this purpose, a mathematical modeling based on experimental data from a test bench with industrial components is presented to separate the drive train specific properties. This allows the system behavior to be modeled more accurately and used for control approaches.}, author = {Leipe, Valentin and Steinle, Lukas and Bikuña, Xabier Agirre and Lechler, Armin and Verl, Alexander}, booktitle = {2024 European Control Conference (ECC)}, doi = {10.23919/ECC64448.2024.10590860}, month = {06}, pages = {2460-2466}, title = {Modeling and Identification of Load-Dependent Properties for Electrically Preloaded Rack-and-Pinion Drives}, year = 2024 }

To date, the potential of TSN cannot be exploited due to many sub-standards still being under development, gaps in the management and configuration functions, lack of best practices and unresolved integration with higher application layers and domain specific engineering. Previous work, focusing on a modular open source framework for the engineering and management of distributed real-time applications, identified a unified approach for TSN-based endpoints as a key gap. This paper presents a novel endpoint architecture to operate, engineer and manage distributed real-time applications by seamlessly integrating real-time networking and compute. The architecture provides interfaces to a central engineering, allows to integrate centralized as well as distributed network management and offers a unified data management. An abstraction layer for applications allows the efficient use and complements existing open source solutions.}, author = {Oechsle, Stefan and Frick, Florian and Walker, Moritz and Lechler, Armin and Verl, Alexander}, booktitle = {2024 IEEE 20th International Conference on Factory Communication Systems (WFCS)}, doi = {10.1109/WFCS60972.2024.10540878}, issn = {2835-8414}, month = {04}, pages = {41-48}, title = {Endpoint Architecture for Distributed Real-Time Applications Based on TSN}, url = {https://doi.org/10.1109/WFCS60972.2024.10540878}, year = 2024 }

To date, a constant high switching frequency is typically used, based on the strictest requirements of the manufacturing process. The novel adaptive PWM approach dynamically adjusts the switching frequency at runtime to reduce switching losses of the power electronics, while maintaining the required process accuracy. The switching frequency is set based on the requirements of the active operating state of the tooling machine. To determine the optimal switching frequency, a holistic understanding of power dissipation in servo drives is required. A novel modulation-frequency-dependent power dissipation model, incorporating the losses in the drive amplifier and in the motor due to current ripple effects, is presented in this paper. The new model is validated over a wide range of parameters, including different motors, voltages and currents. The evaluation of the model results in a better understanding of the modulation-frequency-dependent power dissipation in servo drives and enables the determination of the optimal PWM frequencies. It is shown that higher energy savings can be achieved at higher voltages, while current ripple effects limit the effectiveness of the adaptive PWM approach for motors with lower power ratings.}, author = {Weiss, Manuel and Frick, Florian and Lechler, Armin and Verl, Alexander}, booktitle = {2024 IEEE 18th International Conference on Advanced Motion Control (AMC)}, doi = {10.1109/AMC58169.2024.10505712}, issn = {1943-6580}, month = {02}, pages = {1-6}, title = {Modulation-Frequency-Dependent Power Dissipation Model for Servo Drives With Adaptive PWM}, year = 2024 }

Typically, safety functionalities for coexistence are based on speed and separation monitoring according to EN ISO 10218. Thereby, a robot should reduce speed or stop completely when an obstacle is too close to avoid collisions. Nowadays, despite this standard, speed and separation monitoring are still realized with static worst-case safety assumptions about the kinematics of humans and robots. Over the years, different static techniques have evolved in the industrial environment like fences, light fences, or camera-based systems where critical zones can be configured. The latter is admittedly more flexible in the configuration but still static during the run-time of the manufacturing system. The static worst-case assumptions result in large unnecessary distances between humans and robots, which leads to inefficient use of space. Therefore, factories are larger than they need to be, which leads to higher costs. This work aims to enhance the use of space in human-robot coexistence applications to make factory layouts more efficient. Therefore, a dynamic minimum distance calculation based on the DIN ISO 15066 with the kinematic information of the coexisting human and industrial robots is provided. It is shown in a simulation that this approach of a dynamic safety distance calculation leads to a reduction of the required space.}, author = {Fischer, Marc and Klingel, Lars and Lechler, Armin and Verl, Alexander and Neubauer, Michael}, doi = {10.1007/978-3-031-27933-1_4}, journal = {Advances in Automotive Production Technology – Towards Software-Defined Manufacturing and Resilient Supply Chains}, pages = {35-45}, title = {Dynamic Safety Distance Determination for Human Robot Coexistence in Industrial Applications}, year = 2023 }

One promising approach is the use of synchronous simulations during the actual operation of cyber-physical production systems (CPPS) to provide valuable insights into possible performance improvements and at the same time reduce the risk of costly downtime. This paper presents a novel concept that enables structured storage of CPPS production data as part of a digital twin that serves as a virtual replica of the physical production environment. In particular, this approach is based on the Asset Administration Shell (AAS), which provides a comprehensive framework for the management of production data and allows for a seamless integration with simulation models. Storing production data in a structured and standardized format can make data queries efficient, facilitate data processing, and provide a solid foundation for simulation model development, calibration, and validation. These simulation models can then be used to identify potential process improvements and test different scenarios, minimizing the risk of disruption to actual production.}, author = {Fur, Shan and Ajdinovic, Samed and Lechler, Armin and Verl, Alexander}, booktitle = {2023 IEEE 28th International Conference on Emerging Technologies and Factory Automation (ETFA)}, doi = {10.1109/ETFA54631.2023.10275580}, issn = {1946-0759}, month = {09}, pages = {1-4}, title = {Towards an Implementation of Simulation Based Digital Twins in Cyber-Physical Production Systems Environments}, year = 2023 }

Impending collisions of moving kinematics, such as robots, can therefore already be detected with the help of simulations before the production system goes into operation.

This work presents a predictive simulation-based approach for the online collision avoidance of automated production systems by enabling virtual commissioning simulations for the application in the operating phase.

The increasing demands on quality and the complexity of the processes cannot always be met by the range of functions that are available in numerical control systems. In the coreless winding of fiber-polymer composites, it is important to keep the roving tension as constant as possible while maintaining a high processing speed. Currently, the winding paths are programmed via a number of control points. This results in a trade-off between lower process properties and higher processing speed with fewer control points. Conversely, finer interpolation of the path can improve process characteristics at lower processing speeds. With interpolation methods that are adapted to the process, new possibilities open up to overcome these trade-offs. This paper presents a spline path planning algorithm based on clothoids. This algorithm considers both the process requirements and the dynamic characteristics of the manufacturing unit. Furthermore, the algorithm is validated on a test contour and compared with established commercial methods.}, author = {König, Timo and Verl, Alexander and Lechler, Armin}, booktitle = {IECON 2023- 49th Annual Conference of the IEEE Industrial Electronics Society}, doi = {10.1109/IECON51785.2023.10312385}, issn = {2577-1647}, month = {10}, pages = {1-6}, title = {Cornuspline Path Planning Algorithm for the Fabrication of Coreless Wound Fiber-Polymer Composite Structures}, year = 2023 }

  @article{Leipe2023, abstract = {Industrial machine tool feed drives are predominantly controlled by cascade control due to their low tuning complexity and inherent robustness. However, the cascaded structure requires the inner cascades to have higher dynamics than the outer cascades, which limits the achievable dynamic accuracy. Direct control approaches, which substitute the position and velocity cascade, offer the potential to utilize the unused potential. A promising approach is model predictive control (MPC), which optimizes the manipulated variable with a plant model along a prediction horizon. However, model uncertainties between the nominal model and the real plant lead to tracking errors. Therefore, this paper presents, a linear MPC (LMPC) and an adaptive MPC (AMPC) with an additional integral action to robustly compensate for model mismatches. Both controllers use a compliant model, are real-time capable with a sample rate of {\$}{\$}{\{}{\{}2{\}}{\backslash},{\backslash}textrm{\{}kHz{\}}{\}}{\$}{\$}and consider state and input space constraints. The AMPC accounts for position-varying stiffness and friction. The controllers are experimentally compared with classical P-PI cascaded control on a ball screw drive. They show a tracking error reduction of {\$}{\$}{\{}{\{}37{\}}{\{}{\backslash},{\backslash}{\%}{\}}{\}}{\$}{\$}(LMPC) and {\$}{\$}{\{}{\{}44{\}}{\{}{\backslash},{\backslash}{\%}{\}}{\}}{\$}{\$}(AMPC) during a high speed motion profile and an increase in bandwidth of {\$}{\$}{\{}{\{}180{\}}{\{}{\backslash},{\backslash}{\%}{\}}{\}}{\$}{\$}(LMPC) and {\$}{\$}{\{}{\{}184{\}}{\{}{\backslash},{\backslash}{\%}{\}}{\}}{\$}{\$}(AMPC), resulting in significantly improved dynamic accuracy.}, author = {Leipe, Valentin and Hinze, Christoph and Lechler, Armin and Verl, Alexander}, day = 22, doi = {10.1007/s11740-023-01206-6}, issn = {1863-7353}, journal = {Production Engineering}, month = {05}, title = {Model predictive control for compliant feed drives with offset-free tracking behavior}, url = {https://doi.org/10.1007/s11740-023-01206-6}, year = 2023 }

Wire harnesses have an infinite number of degrees of freedom, such that they change their shape continuously during manipulation. As of today, the human's ability to perceive the wire harness and deal with its shape changes, is unmatched by any technical solution. Therefore, wire harnesses are still installed manually. This paper proposes a concept for wire harness localization and applies it for robotic wire harness installation. The concept uses two stereo cameras, one to perceive the shape of the wire harness and obtain rough position estimates of wire harness components, and a second for accurate 6D pose estimation of the individual components. The concept is evaluated with a case study on localization in a car chassis, where the accuracy and limitations of the concept are investigated by practical experiments.}, address = {Cham}, author = {Wnuk, Markus and Zürn, Manuel and Paukner, Matthias and Ulbrich, Sascha and Lechler, Armin and Verl, Alexander}, booktitle = {Advances in Automotive Production Technology -- Towards Software-Defined Manufacturing and Resilient Supply Chains}, editor = {Kiefl, Niklas and Wulle, Frederik and Ackermann, Clemens and Holder, Daniel}, isbn = {978-3-031-27933-1}, pages = {333--343}, publisher = {Springer International Publishing}, title = {Case Study on Localization for Robotic Wire Harness Installation}, year = 2023 }

  @inproceedings{10260646, abstract = {Branched deformable linear objects, like wire harnesses, are vastly used in the electrical industry to interconnect multiple electronic components while allowing small relative motions. Their deformable nature gives them an infinite-dimensional configuration space, which is challenging for robotic manipulation and requires sensor feedback about the actual configuration. Cameras have been used before in automation attempts as sensor feedback of branched deformable linear objects. However, image processing is sensible to occlusions and unstructured environments. This paper presents a method of using deep learning-based instance segmentation networks to extract topological features like connectors, clips, branch points and overlapping points on the branched deformable linear object. The topological features originate from features that can be used for matching a stretched representation of the branched deformable linear object to its sensor representation. Our results show that the network is capable of extracting the features for different datasets with high accuracy. Furthermore, this paper evaluates the use of preliminary results in the training process to facilitate annotation by predicting the labels. For now, this paper only uses 2D images of the branched deformable linear objects. Future work will also use depth images, such that individual deformable linear object features, such as length or radius, can be extracted from the images. We anticipate the usage of wire harness automation with robotic manipulation, augmented reality support of the worker or quality control of wire harnesses.}, author = {Zürn, Manuel and Kienzlen, Annika and Klingel, Lars and Lechler, Armin and Verl, Alexander and Ren, Shiyi and Xu, Weiliang}, booktitle = {2023 IEEE 19th International Conference on Automation Science and Engineering (CASE)}, doi = {10.1109/CASE56687.2023.10260646}, issn = {2161-8089}, month = {08}, pages = {1-6}, title = {Deep Learning-Based Instance Segmentation for Feature Extraction of Branched Deformable Linear Objects for Robotic Manipulation}, year = 2023 }

  @inproceedings{10161483, abstract = {This paper presents a new method for correspondence estimation between a previously known topology of a branched deformable linear object and an image representation from a 3D stereo camera. Although frequently encountered in production, robotic deformable linear object manipulation still lacks reliable sensor feedback. Especially for branched deformable linear objects, such as wire harnesses, correspondence estimation is very challenging. Due to their flexible nature, they have an infinite-dimensional configuration space, such that visual appearances of the same object can vary strongly. Knowing the correspondence is vital for various applications, e.g., estimating valid grasping positions for robotic wire routing or augmented reality support for workers. Therefore, this paper presents a method for matching the topology of a branched deformable linear object to camera sensor data. Asymmetries in the wire harness design reduce the solution space by comparing the known topology of a model to the topology extracted from sensor data. The problem of finding the most likely solution to the matching problem requires features extracted from camera images. These features are used to construct a graph-based topology representation, which can then be matched to a graph-based topology representation of the known branched deformable linear object. The presented method is evaluated using multiple different non-overlapping configurations of a wire harness, showing the effectiveness of a graph-based segment matching approach.}, author = {Zürn, Manuel and Wnuk, Markus and Lechler, Armin and Verl, Alexander}, booktitle = {2023 IEEE International Conference on Robotics and Automation (ICRA)}, doi = {10.1109/ICRA48891.2023.10161483}, month = {05}, pages = {7097-7103}, title = {Topology Matching of Branched Deformable Linear Objects}, year = 2023 }

  @article{noauthororeditor, abstract = {To ensure a safe environment for human-machine interaction through signal processing and to process big data from intelligent production systems, increasingly powerful computational hardware is required. Central Processing Unit (CPU) based systems are reaching their load limits when processing large amounts of data. This paper presents a hardware-software architecture for Field Programmable Gate Array (FPGA) based platforms for high-frequency data evaluation using capacitive sensor arrays as an example. The architecture includes on the one hand a concept for hardware-acceler-ated sensor data processing and on the other hand the methodology for reading out capacitive sensor arrays. The focus is on simple and easily scalable electronics as well as a dynamic data processing module that can execute and deterministically process complex algorithms with large amount of data based on flexible rules using hardware acceleration. The presented concept was implemented on a FPGA based hardware platform. This allowed the signal processing of 100 sensor values with a resolution of 32 Bit each by 3 pipelined rules, a second order IIR-filter, a 10-times linear interpolation and an averaging algorithm at a task cycle of 1kHz. For the capacitance measurement validation, a custom developed Printed Circuit Board (PCB) with 6 channels is connected to the FPGA platform. It was shown to be capable of a robust and deterministic capacitance measurement at intervals of 1ms with capacitance values from Femto- to Nanofarad. Due to its easy scalability, the method can be used, for example, to completely cover a robotic arm similar to human skin, fully evaluate its measurement signals and therefore increases Human Machine Interaction (HMI).}, author = {Bubeck, Wolfgang and Frick, Florian and Verl, Alexander}, booktitle = {ISR Europe}, eventdate = {June 20 - 21 2022}, isbn = {978-3-8007-5891-3}, pages = {174-179}, title = {Hardware-Accelerated Data Processing of Capacitive Sensor Arrays for Industrial and Service Robotic Applications}, url = {https://ieeexplore.ieee.org/document/9861814}, volume = 54, year = 2022 }

The automation of production systems is one of those fields. Normally, programming a control system defines the automation strategy. Previous contributions by the authors have shown that a so-called agent can learn automation strategies for production systems using a Reinforcement Learning setup. However, the development of the reward function for the agent can be challenging and needs Reinforcement Learning domain knowledge. This paper introduces a novel approach in combining Test-Driven Development with Reinforcement Learning in order to solve the problem of a suitable reward function. In the presented approach predefined test cases are used to derive rewards for the agent. The use of an automated test framework allows for continuous learning sequences until all test cases are passed. An application example of a robot cell is used to demonstrate the novel approach and verify its suitability and usability. The first application shows promising results for further examination towards more application scenarios.}, author = {Jaensch, Florian and Kübler, Karl and Schwarz, Elmar and Verl, Alexander}, doi = {https://doi.org/10.1016/j.procir.2022.09.043}, issn = {2212-8271}, journal = {Procedia CIRP}, note = {15th CIRP Conference on Intelligent Computation in ManufacturingEngineering, 14-16 July 2021}, pages = {103-108}, title = {Test-Driven Reward Function for Reinforcement Learning: A Contribution towards Applicable Machine Learning Algorithms for Production Systems}, url = {https://www.sciencedirect.com/science/article/pii/S2212827122011970}, volume = 112, year = 2022 }

The application of lightweight construction principles in combination with circular production processes offers a comprehensive approach to this problem. The newly developed zero-waste formwork production method, based on the additive manufacturing of water-soluble sand mixture, enables to produce geometrically complex concrete structures and to reuse formwork material repeatedly in production cycles. This paper demonstrates the potential of this method for the production of the topologically optimised concrete single-span beam with spatial lattice structure (Fig. 1). First, a brief overview of the method will be given, followed then by a description of the design and production of the concrete component under the consideration of production parameters.}, address = {Cham}, author = {Kovaleva, Daria and Nistler, Maximilian and Verl, Alexander and Blandini, Lucio and Sobek, Werner}, booktitle = {Proceedings of the 3rd RILEM International Conference on Digital Fabrication with Concrete (Digital Concrete 2022)}, editor = {Buswell, Richard and Blanco, Ana and Cavalaro, Sergio and Kinnell, Peter}, isbn = {978-3-031-06116-5}, pages = {3--8}, publisher = {Springer International Publishing}, title = {Zero-Waste Production of Lightweight Concrete Structures with Water-Soluble Sand Formwork}, year = 2022 }

To open up new areas of application for industrial robots, an increased dynamic path accuracy has to be obtained. Therefore, this paper addresses this issue by a gain-scheduled drive-based damping control for industrial robots with secondary encoders. For this purpose, a linear parameter-varying (LPV) model is derived as well as a system identification method is presented. Based on this, a gain-scheduled drive-based LPV damping control design is proposed, which guarantees stability and performance under variation of the manipulator configuration. The control performance of the approach is experimentally validated for the three base joints of a KUKA KR210-2 industrial robot. The approach realizes a trade-off between ease of implementation and control performance as well as robustness.}, author = {Mesmer, Patrick and Hinze, Christoph and Lechler, Armin and Verl, Alexander}, booktitle = {2022 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM)}, doi = {10.1109/AIM52237.2022.9863417}, issn = {2159-6255}, month = {07}, pages = {1706-1713}, title = {Gain-Scheduled Drive-based Damping Control for Industrial Robots}, year = 2022 }

  @inproceedings{9729274, abstract = {Cycloidal drives (CDs) are precision transmissions that are often installed in the joints of industrial robots (IRs) with high payloads. It is well known that the hysteresis behavior of the CDs has a significant influence on the dynamic path accuracy of IRs. In contrast to harmonic drives (HDs), which are commonly used in lightweight robots, less literature has been published on the dynamic behavior of robot joints with CDs. Thus, this paper investigates the hysteresis behavior of robot joints with CDs. For the representation of the hysteresis behavior, a nonlinear auto-regressive with exogenous inputs (NARX) model is proposed and compared to a Bouc-Wen model. Both, the data-driven NARX and the Bouc-Wen model are investigated experimentally in terms of their capability for representing the hysteresis behavior of CDs. The quality of the models is validated using a laboratory setup that mimics the drivetrain of a robot joint of the high payload class.}, author = {Mesmer, Patrick and Nagel, Patrick and Lechler, Armin and Verl, Alexander}, booktitle = {2022 IEEE 17th International Conference on Advanced Motion Control (AMC)}, doi = {10.1109/AMC51637.2022.9729274}, issn = {1943-6580}, month = {02}, pages = {358-363}, title = {Modeling and Identification of Hysteresis in Robot Joints with Cycloidal Drives}, year = 2022 }

Future factories will rise to this challenge by employing stationary and mobile Cyber Physical Systems (CPS) which need to exchange various information. With mobile systems, this should be done wirelessly. This paper evaluates a previously proposed concept for a deterministic wireless communication system based on LTE. The concept combines LTE for data transmission with GPS for time synchronization and a time-based control scheme to enable a deterministic exchange of control information. To conduct experimental evaluation, an implementation of the concept is necessary. A prototypical implementation using off-the-shelf hardware and custom software is presented. Using two exemplary test cases, the concept and implementation are evaluated with regard to the overall system latency and the quality of the time synchronization of the internal clocks. The level of synchronicity of coordinated output values after transmitting the corresponding set-point values over the communication system is evaluated in another exemplary test case using a total of three communication end devices. With a measured maximum offset of 814 &#x00B5;s between the synchronized output of two receivers, the concept and implementation stand validated and deemed feasible.}, author = {Neher, Philipp and Lechler, Armin and Verl, Alexander}, booktitle = {2022 8th International Conference on Mechatronics and Robotics Engineering (ICMRE)}, doi = {10.1109/ICMRE54455.2022.9734108}, eventdate = {10.02.2022-12.02.2022}, isbn = {9781665483773}, language = {English}, month = {02}, pages = {157-162}, publisher = {Institute of Electrical and Electronics Engineers Inc.}, title = {Experimental Evaluation of the Deterministic Wireless Communication System Industrial LTE}, url = {http://icmre.org/}, venue = {Virtual, Munich, Germany}, year = 2022 }
