摘　　要：为提高电动汽车续航里程、运行特性和安全可靠性,提出一种电动车用多盘式永磁同步电机协同优化与容错控制方法。首先,建立多盘式永磁同步电机数学模型,提出基于效率MAP图的多盘式永磁同步电机效率优化控制策略,并对多盘式永磁同步电机的容错控制方法进行分析。其次,在效率优化的基础上,提出一种转矩协同控制策略,利用模糊控制进行转矩波动优化。最后,针对所提出的控制策略进行仿真分析和整车测试,结果表明模块化多盘永磁同步电机协同优化驱动系统具有较宽的高效率区间,拓宽了系统效率平台,增加了续航里程,改善了系统运动特性。多盘电机冗余容错功能提高了安全可靠性,具有重要的理论研究意义和应用价值。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.
