Abstract

The optimal strategies for torque ripple restraint of direct torque control (DTC) strategy of Permanent magnet synchronous motor (PMSM) in low-speed of electric vehicle are studied in the paper. The subdivision of voltage vector control strategy and seven-stage hysteresis comparator control strategy are proposed to restrain torque ripple. The optimal DTC strategies models for PMSM are established and simulated in the MATLAB/Simulink. The simulation results are gained to verify effectiveness of the optimal strategies.
