摘要
建立电动助力转向系统的力学模型,并对系统电动机在比例控制和比例加微分控制下汽车电动助力转向系统特性进行分析,对系统的频率特性和时间响应进行数值仿真,分析比例系数和微分系数对系统特性的影响,研究参数变化下系统特性的变化规律,为优化控制规律提供依据。
A mechanics model of electric power steering （EPS） system is set up in this paper. The characteristics of EPS are analyzed in theory. Under the case that EPS motor is in the control of a pure proportion controller and proportion-plus-derivative controller. The frequency response and time response of the system are numerically simulated. The authors also consider the effects of the proportional and derivative coefficients to EPS, study the variational rule of the system property on the effect of variation of the coefficients, and provide basis for optimizing the control law.
