| 摘 要： | 用转向系统的时域响应、转向灵敏度频域响应来表示电动助力转向汽车的转向操纵稳定性能,重点分析了PD控制参数对转向灵敏度的影响。M atlab仿真分析表明:基于PD控制算法的控制器可降低系统超调量,使系统稳定时间下降,但是系统反应时间却随之上升。当Kp=50,Kd=0.4时,系统有较好的响应特性,此时执行指令误差小、调节时间短、谐振频率处于最佳。

| Abstract: | With the time domain response steering system and the frequency domain response of steering sensitivity indicating the stability of electric power steering,PD parameters impact on steering sensitivity is analyzed.Matlab simulation analysis shows that PD parameters can reduce the overshoot of system,but system stable time reduces whereas the system response time increases.When PD parameters are Kp=50 and Kd=0.4,the system has a good response,fewer errors in executing instructions,less regulation time,and per... |
