In this papec a sliding mode controller based on model reference adaptive control (MRAC) is proposed j,+r PMSMsystem. The controller employs a sliding mode control (SMC) strategy in order to reduce the complex identfication of MRAC. By employing the proposed control scheme, the response of the PMSM system will keep pace with the reference model strictly and is insensitive to system uncertainties and load disturbance. This kind of controller achieves a good result in simulations.
