In this paper, a vector-controlled induction motor drive with efficiency optimization using a loss model based approach is presented. To improve the robustness of the control system, a self-tuning controller has been designed. On-line estimators for rotor resistance and magnetizing inductance are included in the controller to improve performance. Analysis, modeling and simulation results are presented to demonstrate the validity of the proposed method.
