摘要

Proposes the application of Extended Kalman Filter(EKF) observer on the direct torque controKDTC) of PMSM. EKF observes the stator voltage and current to estimate the rotor speed, rotor position, stator flux linkage and torque. Based on the estimation, the sensorless speed control system of PMSM is built up. The EKF observer provides a good optimal state estimation of PMSM which is a system of nonlinear, parameter variations and disturbance. The results of simulation show that this method can estimate the state variables accurately, improve the performance of direct torque control of PMSM, especially in the low speed region.
