Abstract: In this paper,the mathematic model of the permanent magnet synchronous motor(PMSM)was analyzed first,and then the simulation model of the nonsalientpole PMSM was established in the simulink of the Matlab  based on the mathematic model of the PMSM.The control system adoped the classical three-close-loop structure.In this control system,the id=0 control strategy in current loop and PI control were used in speed loop,and also the fuzzy PI control in position loop which was realized by programming in the Matlab.Given the way of establishing the simulink model of every module in the Matlab given in this paper,and the transient processes of position,speed and torque were simulated and analyzed for the actual parameters of system project at the time of sudden loadadd/unload.The simulation results,show the system is of good antiinterference and able to track the given position and speed quickly and accurately.
