摘　　要： 对电动汽车控制系统进行了研究,提出了电动汽车建模和控制系统建立的方案。电动汽车的电机和平台子系统都是派生的,再根据车轮转动时的电机特性和表面条件,建立数学模型和相应的仿真模型。设计了一种双环控制系统,在Matlab/Simulink中建立相关模型,并测试其是否可以应对不同的干扰条件,包括总质量和路面条件的参考信号变化和扰动形式的变化,以保证车辆行驶稳定性和乘坐舒适性。 This paper studies about the electric vehicle control system and presents a solution of the modeling and control system of electric vehicle. The detailed and accurate mathematical models and corresponding simulink models of both electric vehicle＇s electric machine and platform sub-systems was derived and coupled with the wheel rotational velocity via characteristics of the electric machine and surface conditions. It designs a double loop control system,and sets up the model in Matlab/Simulink to test whether it can deal with different interference conditions,and change the reference signal including total quality and road conditions and disturbance form changes to meet the driving stability and ride comfort.
