摘要
为提高电动助力转向(EPS)系统控制的精度,必须对传感器的输出信号进行动态补偿。阐述了EPS系统的结构原理,建立了EPS状态空间方程,设计了PID闭环控制器,并对参数进行了整定。仿真结果表明,通过对信号的滤波及动态补偿,能够显著抑制信号噪声的干扰,提高了EPS系统的控制质量。
In order to increase the control accuracy of EPS,dynamic compensation must be made to output signals of sensors.This paper discussed the structure and principle of EPS system,established the state space equation of EPS, designed PID close loop controller,and set the parameters.The simulation results show that signals filter and dynamic compensation can restrict the disturbance of signals noise significantly,and increase the control quality of EPS system.
