Abstract：The electronic pole-changing with exponential response torque tracking of five-phase induction motor (FIM) suffers from the problem of unsmooth operation. The analysis shows that that the rotor flux saturation is one of the main reasons. Therefore, a rotor flux optimization (RFO) electronic pole- changing control strategy is proposed considering the flux saturation. The superposition of the rotor flux of two control planes during the process of electronic pole-changing is the cause of flux saturation. The control function of the rotor flux is thus designed by the constraint functions of flux amplitude and electromagnetic torque to make the rotor flux approach the critical value, which optimizes the rotor flux control. Based on the Speedgoat hardware in the loop experimental platform of FIM, the proposed RFO method is verified through an experiment, and the electronic pole-changing control strategies of exponential response torque tracking with and without RFO are compared. The experimental results show that the proposed strategy reduces the speed fluctuation by 50% and the torque fluctuation by 67%, which effectively improves the smoothness of the motor during electronic pole-changing process.
