摘要：
In order to improve the cruising range, operation characteristics and safety reliability of electric vehicles, this paper proposed a cooperative optimization and fault-tolerant control method for axial flux permanent magnet synchronous motor (AFPMSM) for electric vehicles. Firstly, the mathematical model of AFPMSM was established. The efficiency optimization control strategy of AFPMSM based on efficiency map was proposed and studied, and the fault-tolerant control method of AFPMSM was analyzed. Secondly, based on efficiency optimization, a torque cooperative control strategy was proposed, and fuzzy control was used to optimize torque ripple. Finally, the simulation experiment and the vehicle test were carried out for the proposed control strategy. The results verify that the modular AFPMSM cooperative optimization drive system has a wide efficiency range, broadens the system efficiency platform, increases the cruising range and improves the mileage and system's motion characteristics. Multi-disk motor redundancy and fault tolerance improve safety and reliability, which have important theoretical research significance and practical application value. © 2019 Chin. Soc. for Elec.
