The Extended kalman filter (EKF) has been found wide application in the sensorless control of induction motor (IM) because of its good steady and dynamic behaviour,disturbance resistance, and fast convergence. This paper presents a novel speed sensor

The training techniques, allows a wide range of use of the asynchronous machine with good performance, tell her great robustness, reliability and electromagnetic low cost. The vector control strategy takes into account the dynamic structure of
