车辆主动前轮转向与主动悬架的自抗扰控制方法
Active disturbance rejection control method of active frontwheel steering and active suspension system of vehicle
摘要
Abstract
In order to realize the integration and decoupling control of the active front wheel steering(AFS)system and the active suspension system(ASS),the active disturbance rejection(ADR)method for integrated control of two subsystems is proposed.The active disturbance rejection controllers(ADRC)of the AFS and the ASS are designed and the double lane change test is carried out under the road disturbance input.The path tracking performance,the steering road feel,the steering sensitivity and the ride performance of vehicle are studied,and the characteristics of the integrated control system is analyzed by comparing with the system without control and the AFS-only/ASS-only system.The results show that the ADR integrated control of the AFS and the ASS can improve steering performances and comfortable performances,and increase the handling stability and the ride comfort.The design of the ADRC needs no accurate mathematical models and the interference suppression needs no disturbance models,the control method is simply and in good robustness.The decoupling control between the steering and suspension and the suspension each other can be easily realized by the ADR method.关键词
