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可能性。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方法确定该控制系统的增益系数。
Automobile suspension system is a typical nonlinear system,which is based on the magnetorheological fluid damper. By analyzing the behavior of the system under the sinusoidal force,the possibility of chaos was proved in this paper. Further more,the nonlinear feedback method was used to control the chaos,and the Melnikov method to get the gain coefficient.
