This paper presents a speed sensorless sliding mode control strategy of interior permanent magnet synchronous motor (IPMSM). The estimation of the rotor position and speed is achieved by using a model reference adaptive system (MRAS) to alleviate the need of physical sensors. Sliding mode control is able to increase the performance of the Fuzzy MRAS observer in terms of, speed reversion and load rejection. Simulation results with IPMSM shows that the designed sensorless sliding mode control based Fuzzy MRAS observer réalises a good dynamic behaviour of the motor with a rapid settling time, no overshoot and has better performance than sensorless vector control PI MRAS observer.
