摘要
由于电动汽车运行工况复杂,而且随着电动汽车运行工况的不同,电动机自身的参数也会随之而改变,如果不对速度控制器的参数或输出进行任何的校正,控制系统的性能便会变差.为解决这一问题,设计了一种基于模糊控制器的电动汽车用永磁同步电动机矢量控制系统.在保留原速度控制器的基础上,利用模糊逻辑处理不确定信息方面的能力,对速度控制器的输出进行实时校正.同时,给出了系统软硬件设计方案.最终实验结果证明了该控制方案的有效性.
As the running condition of EV is very complex and the parameters of PMSM change along with it, the dynamic performance of EV driver will become worse. In order to solve this problem, a system based on fuzzy controller has been designed for EV motor driver. On the basic of keeping the original speed controller, we can use the capability of fuzzy logic in handing uncertain information, and correct the output of the speed controller real - time. A design schema of system software and hardware is given and its validity has been proved by experiment results.
