摘要:
通过建立车辆半车模型的动力学方程,应用随机线性最优控制理论设计了车辆主动悬架LQR控制器,并在Matlab/Simulink环境中构建了实现该控制策略的仿真模型,对仿真结果进行了时域和频域分析,结果表明:具有LQR控制器的主动悬架能有效减小车身加速度和悬架动挠度,可以更好地改善车辆的舒适性.
Abstract:
To establish the dynamics equations of the vehicle half-car model, LQR( linear quadratic regulator)controller of active suspension is designed based on stochastic linear optimal control theory, and a simulationmodel is built in Matlab/Simulink environment for the realization of this control strategy, The analysis of simu-lation results in the time domain and frequency domain shows that active suspension with the LOR controllercan effectively reduce the body acceleration and suspension dellection, and can be used to improve vehicle comfort.
