摘要
基于磁流变减振器的汽车悬架系统具有明显的滞后非线性,这直接导致了系统存在分岔与混沌的可能性。分析了汽车悬架系统在路面单频正弦激励下的受迫振动,揭示了该系统存在混沌运动的可能性,并在此基础上,利用非线性反馈控制方法对这类混沌行为进行了控制,并采用Melnikov方法确定了该控制系统的增益系数。
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 based on this, makes control on this kind of chaotic behaviors by using the nonlinear feedback control method, and determines the gain coefficient by using the Melnikov method.
