Position Tracking Control of Permanent Magnet Synchronous Motor Based on Fuzzy Sliding Mode Principle
2014
Aiming at the anti-jamming capability problem of permanent magnet synchronous motor servo system, a fuzzy sliding mode controller is designed. The sliding mode control enhances the anti-jamming capability of the system, but it also brings chattering to the system which influences the control performance. In order to solve this problem, a fuzzy item is utilized to obtain the gain of sliding mode switching control law. Hence, the switching gain is adjusted in real time according to the sliding mode surface . The simulation results show that the system achieves good traceability and anti-jamming capability, the proposed controller has good performance and successfully solves the chattering problem.
