In order to solve the real-time parameter adjustment problem of the speed sensorless vector\ncontrol system for the induction motor, the paper presents a fuzzy self-adaptive method with\nintelligent gain adjustment. By the means of the sensorless vector control for induction motor, adapt\nModel reference adaptive system (MRAS) to achieve the rotor position estimation to improve the\nspeed and estimated accuracy, and then design the out-loop controller to achieve high response of\nspeed control. So applying the method of the fuzzy self-adaptive parameter adjustment, track and\ncorrect controller parameters in time to achieve high dynamic response. The simulation results\nconfirm the validity and effectiveness of the proposed control strategy.
