  @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 }

  @article{NEUBAUER2021103796, abstract = {The precision of machine tools is essentially determined by the feed drive control. To improve the dynamic behavior of elastic feed drives, this paper presents a novel position control concept, substituting the conventional P position controller of the industrial cascade control with a continuous sliding mode controller (SMC) together with a Kalman Filter for state estimation. The novelty of this approach lies in the focus on practical applicability: The underlying PI-cascade structure leads to low commissioning effort and the SMC controller’s parameterization is simplified to a single tuning parameter. A general compliant feed drive model is used as plant, whose parameters usually are already known from commissioning of the velocity controller. The SMC position controller is derived analytically and its stability and damping properties are investigated for the dominating mechanical mode for uncertainties of the model parameters and a wide range of controller gains. The effectiveness of the SMC-PI controller is validated for an industrial ball screw feed drive. Extensive experimental results show a considerable decrease of tracking errors in command tracking, disturbance rejection and for a high speed cutting (HSC) milling experiment compared to P-PI cascade control, while stability margins remain almost independent of the controller gains. The parameterization is discussed on the basis of a theoretical analysis and measuring results. Furthermore, excellent robustness properties regarding model errors are demonstrated.}, author = {Neubauer, Michael and Brenner, Felix and Hinze, Christoph and Verl, Alexander}, doi = {https://doi.org/10.1016/j.ijmachtools.2021.103796}, issn = {0890-6955}, journal = {International Journal of Machine Tools and Manufacture}, title = {Cascaded sliding mode position control (SMC-PI) for an improved dynamic behavior of elastic feed drives}, url = {https://www.sciencedirect.com/science/article/pii/S089069552100105X}, year = 2021 }

  @article{Friedrich2015, abstract = {Abstract The productivity of milling processes is limited by the occurrence of chatter vibrations. The correlation of the maximum stable cutting depth and the spindle speed can be shown in a stability lobe diagram (SLD). The stability is different for different width of cut and can change with the axis positions. Today it is already a great effort to estimate the \{SLD\} only for one position. Many experiments are necessary to measure the \{SLD\} or derive a detailed mathematical model to calculate the SLD. Moreover not only the cutting depth, but also the cutting width should be represented in the SLD. This paper presents a new approach to assess the process stability based on measured acceleration signals. The multidimensional stability lobe diagram (MSLD) are derived during the production using two new continuously learning algorithms. In this paper the application of a continuous learning support vector machine and a continuous neural network is shown. The support vector machine and the neural network are extended to make them capable for continuous learning and time-variant systems. A new trust criterion is introduced, which gives information about the prediction quality of the output for the selected input region. The learned \{MSLDs\} are evaluated against analytically calculated \{MSLDs\} and the learning algorithms can reproduce the analytical results very well. }, author = {Friedrich, Jens and Hinze, Christoph and Renner, Anton and Verl, Alexander and Lechler, Armin}, doi = {http://dx.doi.org/10.1016/j.rcim.2015.10.003}, issn = {0736-5845}, journal = {Robotics and Computer-Integrated Manufacturing }, pages = { - }, title = {Estimation of stability lobe diagrams in milling with continuous learning algorithms }, url = {http://www.sciencedirect.com/science/article/pii/S0736584515001155}, year = 2015 }
