Forschung am ISW

Wir forschen interdisziplinär an Technologien für die Produktion und Automatisierung von Übermorgen. Die industrielle Anwendbarkeit steht dabei immer im Fokus. Unsere Forschungsaktivität umfasst dabei die folgenden Themenschwerpunkte.

Wir haben auch eine Übersichtsliste aller unserer Projekte.



Drive Control

Controlled electrical drives have become an integral part of almost every industry sector. In the field of production engineering, the fast, precise and robust setting of position or speed presents a key challenge. In the area of feed drives, predefined paths have to be implemented exactly and, at the same time, interferences eliminated. The ISW does research in implementing new control methods and structures for improving precision, efficiency or flexibility of drives  in order to open up new applications.



Operation

In order to respond to the growing complexity of today’s machines and plants, the ISW is developing flexible and 3D-supported user interfaces. Here, newest technologies from the gaming industry like Unity3D or Unreal 4 development environment are combined with the latest findings in the field of gamification – the use of game mechanisms in productive operations. The result is an operating concept based on direct interaction with the virtual image of the machine. The cam discs for a transfer press, for example, can thus be programmed by direct moving of the virtual axes, similar to the teach-in mode with robots.



Engineering

For efficiency increase of the development process, the ISW is doing research concerning simulation-based and modular engineering methods. Here simulation models are used as communication and validation platforms, in order to be able to visualize and check functions in early phases of the development process. For facilitating the modelling, methods from modular engineering are applied, which allow the automatic generation of models from functional primitives that are based on a requirement description and to assess them. The method involves that the models grow along and are finally used for the virual commissioning or in maintenance.



Communications

Communication technology plays an important role for machinery and plant engineering. Within the initiatives for industry 4.0 and IoT it has become even more important. The ISW promotes in this context innovations in the field of real-time capable and not capable as well as wired, wireless and powerline communication mechanisms. Besides the specification of communication protocols and profiles this includes also validating and testing. The ISW is further firmly anchored in the Sercos and OPC UA Community.



Mechanical Engineering

In the area of mechanical engineering, the ISW is primarily concerned with the topics machine dynamics, various feed drive concepts, single machine components and new machine kinematics. Experimental investigations of machines and facilities are carried out and all sorts of feed drives like ball screws, rack and pinion, belt and linear direct drives are analyzed metrologically. In addition, new ways of layout and commissioning are developed. In order to meet new technological requirements, novel machine kinematics are developed, designed, constructed and put into operation.



Simulation

Nowadays, the simulative modelling of components, machines and processes presents an indispensable tool for engineers of all disciplines. Simulation technology allows making early statements about the service life of components and their interaction can be verified efficiently. The ISW develops and uses therefore simulation technology through all stages of production engineering: In the field of mechanical analysis of machine components by means of finite element and multi-body methods, in the design of electrical and electronical circuits as well as for the virtual modelling of entire plants and processes for virtual commissioning.



Control Algorithms

For many years, the ISW has been carrying out fundamental research concerning algorithms for control engineering in the context of machine tools and plant engineering. The target is to improve accuracy and finish quality at workpiece machining, to reduce the machine and tool load and to decrease the machining time. For this purpose, the ISW is developing novel interpolation methods, algorithms for collision-free path planning, high-performance control algorithms on basis of FPGA as well as algorithms for kinematic and physical imaging of machines and plants for real-time simulation.



Control Architectures

The control and drive technology benefits strongly from IT developments. Increasing computing power due to multicore, GPU and FPGA systems as well as cloud technology, miniaturization of hardware components and novel software concepts are used efficiently at the ISW for the further development of control and drive systems. Among other things, the ISW contributed significantly to the architecture of current CNC systems, and with the Open Drive Control Platform and test and certification solutions for fieldbus and control systems we have developed other innovative solutions and concepts.
