Abstract

In order to improve the performance of permanent magnet synchronous motor (PMSM), an improved index reaching law is presented by introducing the system state variable to solve the problems such as slow tightening speed and high frequency chattering of traditional index reaching law. A fuzzy sliding mode speed control system for PMSM is designed by adjusting the parameters of the reaching law with fuzzy control, and the simulation results are compared with the traditional index reaching law. The results show that the improved approach law can effectively reduce the high frequency chatting at the origin compared with the traditional index approach law, and the PMSM speed control system has faster response speed, better robustness and dynamic and static performance.
