There is a phenomenon that there is a big overshooting and speed fluctuation in the process of motors speed regulation.The stable characteristics of the system should have better control and real-time response characteristics, but the traditional PI control has been used in the motor, which often cannot meet the requirements of high performance control.In order to overcome some faults in the traditional PI control and optimize the performance of the motor.In this paper, it chooses the permanent magnet synchronous motor (PMSM) as the research object, and speed control system of PMSM based on the fuzzy sliding mode structure control (SMC) strategy is put forward[1-4].The method is simple in the structure, which has fast dynamic response and high steady-state accuracy.Through the simulation test, it shows that the system of the change in the moment of inertia of load has a strong robustness, and smaller overshooting than traditional PI control.The method improves the performance of stable operation, and provides the basis for the design.
