The Research of Speed Feedback Control in Automobile Suspension Chaotic System

The automobile suspension system based on the magnetic fluid damper is a typical hysteretic nonlinear system, which causes the possibility of the branch and chaos existing in the system. By analyzing on the forced vibrations of the automobile suspension system under the single-frequency sinusoidal motivation of the road surface, this paper reveals the possibility of the chaotic movement existing in the system, and in terms of this view point, this kind of chaotic behaviors can be controlled by using the speed feedback control method, and it also provides the academic basis for using the chaos sequence.
