摘要
本文运用车辆动力学理论,建立了半车四自由度主动悬架系统的动力学模型。同时依据最优控制理论设计了主动悬架最优控制器并进行了Matlb+simulink仿真。研究结果表明采用最优控制的主动悬架比被动悬架具有更好的平顺性。
The 4-D model of half-vehicle active suspension system was established based on the vehicle dynamics theoryo By using optimal control theory, the LQG controller was designed and the matlab＋simulink simulation was carried out o The results showed that active suspension have a good ride comfort than the passive suspension .
