英文摘要：

On the basis of mathematical model of PMSM and SVPWM algorithm, the principle and realization of space vector pulse width modulation is introduced. In order to test the correctness of each part＇ s output and provide the necessary parameters for the design, the whole system is simulated by Simulink tool box in Matlab. The system is composed of two control loops which are the inner current-loop and the outer speed-loop. By simulating the specific motor, the waves are presented, the control algorithm id =0 is validated and the simulation results shows the efficiency of model.
