| 摘 要： | 对带有电流变智能阻尼器的汽车半主动悬架系统设计了一种输出反馈变结构控制器。根据滑模运动方程稳定的Hurwitz判据选择滑模面矩阵,实现控制与外界扰动完全解耦。仿真分析了多种激励信号下隔振质量的响应及半主动悬架系统在系统参数摄动下的鲁棒特性。仿真结果表明,变结构控制下半主动悬架系统的隔振效果要远好于最优被动系统,而且对外界扰动有一定的适应性,对系统参数摄动也具有很强的鲁棒性。

| Abstract: | An output feedback variable structure controller was designed for automotive semi-active suspension with electro-rheological(ER) damper.Sliding surface matrix has been selected in accordance with Hurwitz stable judgement of sliding mode motion equation,the control law was completely decoupled from external excitations.The isolated mass response of many kinds of excitations and the robustness of semi-active suspension system with respect to parameter variations were simulated.The simulation results indicated that the performance of semi-active suspension system designed with varying structure control methods are better than those of optimally passive damping,semi-active suspension system has self-adaptability with respect to external disturbances and good robustness with respect to system parameter variations. |
