In this paper, we present the speed sensorless of indirect field oriented control (IFOC) of induction motor (IM). The speed estimator has been designed using extended Kalman filter technique (EKF). According to this method, the rotor speed is obtained from the directly measurable stator voltages and currents. A fuzzy logic controller (FLC) used for the speed and sliding mode controllers (SMC) used for stator currents control to allow a good performance and robustness against the load disturbances. Simulation results are illustrated and demonstrate the effectiveness of the proposed strategy.
