摘要
分析了汽车电动助力转向系统的结构,选择直线型的助力特性曲线进行控制,通过PID控制方法对电机进行控制,建立电机控制的数学模型,并在Matlab/Simulink仿真环境中搭建出电动助力转向系统模型,通过不断地调整控制器参数观察输出结果,直到使系统的控制效果达到最优.
The structure of EPS system was described in the paper.The straight-line assist characteristic cure was chosen to control.Controlling means of PID was used to control the assist motor and estanblish a mathmatical model.The EPS model was constructed by Matlab/Simulink.The observing outcome of the controller parameters was constanlty adjusted until potimized controlling effect of the controling systtem was obtianed.
