Abstract :
This paper proposes the sensorless control system of induction motor using the observer gain tuning and high frequency injection techniques. The high frequency injection is activated by the condition of observer gain k. The high frequency injection technique is based on magnetic saliencies caused by the saturation and high frequency injection.
