Intelligent control is getting much attention in the area of electric drive system.According to the mathematical model of the permanent magnet synchronous motor(PMSM),a novel fuzzy PI intelligent method is proposed to control the speed servo system based on the dynamic model of PMSM.In the double loop of speed servo system the hysteresis current calculator is implemented in the current loop,and in the speed loop the fuzzy PI intelligent control scheme is applied.Several test cases based on PMSM were conducted to confirm the effectiveness of the proposed controller.The simulation results show the improved performance is superior to the traditional PI controller.It works well with high dynamic and static performance,because of its advantage in quick response and good robustness.
