基于达朗贝尔原理建立半车主动悬架动力学模型,采用最优控制理论进行主动悬架LQG控制器设计.在Matlab/Simulink中建立对应的系统仿真模型,采用白噪声路面输入后进行该系统动态特性仿真,并将主、被动悬架特性进行对比分析.仿真结果表明,相对于被动悬架主动悬架性能有明显改善.
基于達朗貝爾原理建立半車主動懸架動力學模型,採用最優控製理論進行主動懸架LQG控製器設計.在Matlab/Simulink中建立對應的繫統倣真模型,採用白譟聲路麵輸入後進行該繫統動態特性倣真,併將主、被動懸架特性進行對比分析.倣真結果錶明,相對于被動懸架主動懸架性能有明顯改善.

Half-vehicle active suspension＇s dynamic model through D＇alembert＇s principle was built and active suspension LQG controller was designed on the basis of optimal control theory.The simulation model was built through Matlab/Simulink and then the Band-Limited White Noise was adopted as the road input to carry out the dynamic performance simulation.The performances of active suspension and passive suspension were compared.The result indicated that active suspension＇s performance was improved obviously,compared with performance of passive suspension.
