Abstract :
This paper presents a new, cheap, and accurate loss model based controller to improve the efficiency and the power factor of speed sensorless controlled induction motor, by calculating the optimal air gap flux. Also the proposed loss model controller verifies stable operation for a high load step disturbance.
