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。
关键词:汽车;电动助力转向;系统特性;理论分析
Abstract :A mechanics model of elect ric power steering ( EPS) system is set up in this paper1 The characteristics of EPS are analyzed in theory1Under the case that EPS motor is in the cont rol of a pure proportion cont roller and pro2 portion2plus2derivative cont roller. The f requency response and time response of the system are numerically simula2 ted1 The authors also consider the effect s of the proportional and derivative coefficient s to EPS , study the variational rule of the system property on the effect of variation of the coefficient s , and provide basis for optimizing the cont rol law1
Key words :Vehicle ; EPS ; System characteristic ; Theoretical analysis
