The traditional current and speed PI control method of Permanent magnet synchronous motor (PMSM) vector control exists problems such as large fluctuation of start-up torque and speed, and bad tracking performance of current etc. Aiming at solving these problems, this paper designed the current regulator which adopted integral separation control strategy and speed regulator with fuzzy-PI double mode control strategy, and simulation model was built in Matlab/Simulation, the simulation result indicated that this improved control system had better dynamic and static characteristic than traditional control system. Finally, experiments based on the proposed method were done to verify the correctness of the conclusion further.
