PREFILTERS IN THE CONTROL OF MECHATRONICS SYSTEMS

Abstract


Many mechanical applications need a way to reduce or eliminate the mechanical vibrations that may appear if the reference signal modifies suddenly. Due to the tuning of the controller, the new reference can be obtained by an aggressive control, which leads to vibrations or a slow response, which leads to the increase of the response time. A solution that allows both vibration elimination and a fast response time is using pre-filters. The area of applications is large: cranes, manipulators, automated machinery etc.

Key words: Mechatronics systems, prefilter, input shaping, trajectory generation, optimization
