基于模糊PID线控转向系统前轮转角控制
The control of front wheel steering angle of steer-by-wire system based on fuzzy PID
摘要
Abstract
Steering system is the important performance index of the passenger car, it is related to the vehicle han- dling stability and comfort. In this paper, the structure and the principle of work are analyzed, and a Simulink joint CarSim simulation model of steer-by-wire system is established by using fuzzy theory so as to control the front wheel steering angle. A fuzzy PID controller based on the vehicle dynamics model is designed for controlling the front wheel steering angle.The simulation results show that, on one hand, the smaller steering wheel angle can achieve a larger front wheel angle and a small transmission ratio at low speed, as a result, the driver performs turns lighter; and on the other hand, the larger steering wheel angle can achieve a small change of front wheel angle and a large transmission ratio at hight speed. The controller can prevent tremors effectively at high speed and improve the stability of the vehicle manipulation.关键词
