In order to reduce the ripples of flux linkage and torque for direct torque control (DTC) and ensure constant inverter switching frequency, permanent magnet synchronous motor (PMSM) DTC based on space vector modulation (SVM) and extended Kalman filter (EKF) is researched in the paper. Simulation results have shown that the inherent advantages of fast dynamic response of DTC are maintained, and flux linkage and torque ripples are effectively reduced. Speed is estimated accurately, and sensorless operation is realized.
