Abstract
This paper proposes a new hybrid method for efficiency optimization of induction motor drives. To do this task, the followings are done. Firstly, the induction motor drive with 3 phases is modeled by using copper loss and core loss to find out the optimal efficiency of the power losses. Secondly, golden section technique is used to optimize the drive efficiency by searching for an optimal value according to the reference rotor flux current. In this way, the electrical input power of the system can also be minimal. Finally, the improved algorithm is proposed to enhance the system response speed and reduce torque ripple. The simulation is done to validate the proposed algorithm. The simulation results show that the proposed algorithm can be better than a convention method such as loss model control (LMC) and search control (SC) in terms of lower torque ripple and higher response speed.
