Abstract: Combined an induction motor speed sensorless bi-sliding mode control system with adaptive sliding mode observer and sliding mode control to solve the influence of operation performance in common induction motor sensorless control system caused by variation of parameter and external load disturbance, built an system simulation model. System simulation experiments prove that the sliding mode control system with adaptive sliding mode observer has properties of better robustness, no overshoot and quick dynamic response when variation of parameter and external load disturbance happen.
