摘要
为了满足电动汽车的驱动要求,达到良好的控制效果,以永磁同步电动机矢量控制技术为基础,提出了一种两后轮独立电机驱动电动汽车的电子差速控制策略,建立了其M atlab/S im u link仿真模型,同时采用混合最优PSO算法对P I参数进行了优化。仿真结果显示,该策略能够使电机表现出很好的快速响应与平稳性,适合独立电机驱动电动汽车的驱动系统。
In order to satisfy the requirement of the driven system of an EV and achieve good control effect, a new strategy of the electric differential control of the two motors of EVs driven by two independent motors was proposed on the basis of the technique of vector control of PMSM and its model was established. The parameters of PI adjusters were also optimized with HMPSO algorithm. The simulation result indicated that the motors gave excellent dynamic and static performances with this strategy, so it＇ s adapt to the driven system of EVs.
