N2 - In this paper, a fuzzy sliding mode control algorithm with variable rate reaching law is designed for the permanent magnet synchronous motor (PMSM) vector control system. Firstly, a nonlinear sliding mode surface is designed, and an SMC algorithm combining exponential reaching law and terminal sliding mode control is proposed. Then in order to solve the chattering problem of sliding mode control system, fuzzy control is introduced. The distance between system state point and sliding mode surface is used to set fuzzy rules to realize the dynamic adjustment of the sliding mode reaching speed. Finally, the PMSM vector control system model is established in MATLAB/Simulink environment, and the speed control of PMSM under sudden change of load torque is simulated. Simulation results show that the PMSM vector control system with improved fuzzy SMC algorithm has better dynamic response characteristics and robustness, and the anti-interference ability of the system under sudden change of load torque is improved.
