Abstract

In order to improve the cruising range, and operating characteristics, the safety and reliability of electric vehicles, a collaborative optimal control strategy of multi disk permanent magnet synchronous motor for electric vehicles is proposed. Firstly, the mathematical model of the multi disk PMSM is established, and the efficiency optimization control strategy based on the efficiency map is proposed, and the efficiency optimization control method of the multi disk PMSM is analyzed. Secondly, on the basis of efficiency optimization, a torque collaborative control strategy is proposed, in which fuzzy control is used to optimize the torque fluctuation. Finally, the simulation analysis and vehicle test are carried out for the proposed control strategy. The results show that the modular multi disk PMSM collaborative optimization drive system has a wider range of high efficiency, widens the system efficiency platform, increases the range, and improves the system motion characteristics, which has significantly theoretical research significance and application value.

电动汽车多盘永磁同步电机协同最优控制策略

为了提高电动汽车的续航里程、运行特性、安全性和可靠性，提出了一种电动汽车多盘永磁同步电机协同最优控制策略。首先，建立了多盘永磁同步电机的数学模型，提出了基于效率图的效率优化控制策略，并对多盘永磁同步电机的效率优化控制方法进行了分析。其次，在效率优化的基础上，提出了一种转矩协同控制策略，采用模糊控制对转矩波动进行优化。最后，对所提出的控制策略进行了仿真分析和车辆试验。结果表明，模块化多盘PMSM协同优化驱动系统具有更宽的高效范围，拓宽了系统效率平台，增加了范围，改善了系统运动特性，具有显著的理论研究意义和应用价值。
