| 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周期激励下的受迫振动,揭示了该系统振动存在混沌的可能性,并在此基础上,利用x|x|形式的非线性反馈控制方法对这类混沌行为进行了控制,为利用混沌序列提供了理论基础。

| Abstract: | The automobile suspension system based on the magnetic fluid damper is a typical hysteretic nonlinear system ,which causes the possibility of the branch and chos existing in the system. By analyzing 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 in the system, and based on this ,makes control on this kind of chaotic behaviors by using the nonlinear feedback control method with piecewise-quadratic function in the form of x lxl. This provides the academic basis to utilize chaos sequence. |
