New hybridmodel for efficiency optimization of inductionmotor drives (IMD) is presented in this paper. It combines two strategies\r\nfor efficiency optimization: loss model control and search control. Search control technique is used in a steady state of drive and\r\nloss model during transient processes. As a result, power and energy losses are reduced, especially when load torque is significant\r\nless related to its rated value. Also, this hybrid method gives fast convergence to operating point of minimal power losses and shows\r\nnegligible sensitivity to motor parameter changes regarding other published optimization strategies. This model is implemented in\r\nvector control induction motor drive. Simulations and experimental tests are performed. Results are presented in this paper.
