摘要
具有滞后非线性的汽车悬架系统具有明显的非线性,这直接导致系统存在分岔和混沌的可能性。为此分析其在路面正弦周期激励作用下发生受迫振动时的运动情况,揭示该系统存在混沌现象,并利用小波函数形式控制器对其混沌行为进行控制。数值模拟表明:该控制方法具有效性与可行性。
Vehicle suspension system with hysteretic nonlinearity is a typical nonlinear system.The behavior of the system under road sine excitations is analyzed,and the possibility of chaos is proved in the paper.Furthermore,the wavelet function controller is used to control the chaos and to guide the chaotic motions towards regular motions.Numerical simulation shows the effectiveness and applicability of this method.The results are helpful for the analysis and optimal design of the vehicle suspension system.
