Abstract :
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 chain using SVPWM is the smallest and the performance of robustness is the best. PMSM vector control system using SVPWM is benefit for elevator steady operation.
