PMSM has been used widely in elevator speed control system. Based on the mathematical model of PMSM and algorithm of inverter (CFPWM, SPWM, SVPWM), PMSM vector control systems are built. By the software of MATLAB/Simulink, the control systems using three inverter methods of CFPWM, SPWM, SVPWM are comparative simulated and analyzed. The results show that the oscillating of torque, speed, and magnetic...
