Abstract :
This paper presents a robust sensorless Direct Torque Control (DTC) method for induction motor (IM) for estimation of stator flux components and rotor speed based on the Modified Kalman Filter (MKF). The model of IM and its MKF models in Matlab /Simulink simulation environment are developed. The proposed MKF speed and flux estimation method is also proved insensitive to the IM parameter variations. Simulation results demonstrate a good performance and robustness.
