Machine Learning Approach

Die Lageregelung von konventionellen Industrierobotern ist nicht auf den dynamischen Fräsprozess ausgelegt. Eine Möglichkeit, das Verhalten der Regelkreise zu optimieren, ist eine modellbasierte Momentenvorsteuerung, welche in dieser Arbeit aufgrund vieler Vorteile durch einen Machine-Learning-Ansatz erweitert wird. Hierzu wird die Umsetzung in Matlab und die simulative Evaluation erläutert, die im Anschluss das Potenzial dieses Konzeptes bestätigt.   The position control of conventional industrial robots is not designed for the dynamic milling process. One possibility to optimize the behavior of the control loops is a model-based feed-forward torque control which is supported by a machine learning approach due to many advantages. The implementation in Matlab and the simulative evaluation are explained, which subsequently confirms the potential of this concept.

The wish for shorter through-put times in the industrial production is connected with higher requirements on the dynamic of industrial robots. These are susceptible to vibrations due to the combination of serial kinematics, flexible gears and the drive-sided position control of the axes. In order to counteract this circumstance, an approach to reduce vibrations via semi-active damping is presented in this article. The potential of the method is demonstrated by means of a forward dynamic simulation.

Sensor Control

For securing and increasing the quality of various material processing technologies a flexible sensor data integration is indispensable. Hence, a powerful and configurable sensor-robot-system was designed and implemented, integrating sensor data into industrial robot controls within the interpolation or the position control clock rate. Different controllers were designed and the system responses of the control loops were simulated and optimized by an efficient control design tool. Experimental results on the achievable path accuracy are presented. Finally, some application for the developed sensor control loops are introduced.

This paper suggests a compensating method of flux fluctuations in permanent magnet of AC servo system. after analyzing the characteristics and control measures of flux fluctuations, the compensation strategy for reducing the effect of flux fluctuations on electromagnetic torque is put forward. Though the simulation experiments it is shown that the flux compensation method for improving the position control accuracy of the movers when their running at high speed is proved to be positive effective. For CNC machine tools, industrial robots and other occasions involving sophisticated movement, synchronous servo motors in permanent magnet are usually driven by high-performance sine wave. In order to obtain good control performance, the high demands are put forward for reducing the torque fluctuations Torque fluctuations are an important factor to affect the stability of low speed servo drive system, high-speed stability and precision position control. There are many factors causing torque fluctuations, in which the flux fluctuations in permanent magnet are an important one.
