摘要：
Electric vehicles often operate under the conditions of frequent start，stop, acceleration，deceleration and variable load, and the efficient control under wide speed range is the key problem. The efficiency optimization method of modular axial flux permanent magnet synchronous motor (AFPMSM) is studied in this paper. First, aiming at the efficiency optimization of stator unit in motor module, a loss minimization control method using online compensation of equivalent loss resistance is proposed, and the optimal control current reference is obtained based on the loss model. Then, according to the efficiency distribution of the module and the genetic algorithm, the torque allocation strategy of each module and each unit in the module is designed to realize the efficiency optimization of the multi-module system. Finally, the simulation and experiment results show that the proposed method can effectively reduce the loss of the drive system, increase the high efficiency range and improve the endurance mileage of electric vehicles. ©2023 Chin.Soc.for Elec.Eng.
