This paper presents the estimation of speed, rotor position and load torque of a robust
sensorless Direct Torque Control (DTC) method for Permanent Magnet Synchronous Motor
(PMSM) based on The Extended Kalman Filter (EKF). The model of PMSM and its EKF
models in MATLAB /Sirnulink simulation environment are developed. The proposed
EKF speed position estimation method is also proved insensitive to the PMSM parameter
variations. Simulation results demonstrate a good performance and robustness.
