Study on the Control System of the Electro-Controlled Steering Damper Based on Magnetorheological Fluid

Abstract:

This paper introduces a kind of electro-controlled steering damper’s structure and working principle which uses the magnetorheological fluid as the working medium. In order to design the controll system of the electro-controlled steering damper, the model of the steering system and the damper based on magnetorheological fluid are established through the dynamic equations, and a PID controller is used. At last, the paper simulates the controll system using a simulation language Modelica on Works, which is a simulation flatform for comp lex physical system modeling and simulation. The results show that the damper can effectively increase the stabilizing speed of the steering system, decrease the over run of the vehicle’s yaw speed, and improve the vehicle’s steering stabilization, especially when the vehicle running in high speed.
