| Abstract: | This paper confirms the power-assisted characteristic curve of EPS(electric power steering).Based on this curve,it designs the power-assisted controller to obtain the controlling goal of electrical power-assisted steering by using some theories such as feed forward control,feedback control,PI control and lagging-leading correction.By simulating and analyzing the closed-loop frequency characteristic curve of power-assisted controller,the closed-loop frequency characteristic in the noise effect of sensor and the closed-loop amplitude characteristic curve under the road disturbance,it shows the EPS system with power-assisted controller can improve the handiness and stability of steering system. |
