| 摘 要： | 应用汽车系统动力学理论,建立了七自由度主动悬架的动力学模型。根据线性二次型最优控制原理设计了主动悬架线性二次型(LQR)控制器,并构建了实现该控制策略的主动悬架控制仿真模型。仿真结果表明:对主动悬架进行最优控制,能够有效地降低车身垂直振动加速度、车身侧倾角加速度和俯仰角加速度。

| Abstract: | An active suspension dynamic model with 7 degrees of freedom is established by applying the dynamics theory.The linear-quadratic regulator(LQR)controller of active suspension is designed based on the theory of linear-quadratic optimal control,and the active suspension simulation model that realizes this LQR control strategy is built.The simulation results show that the optimal control of active suspension can reduce vertical vibration acceleration,roll and pitch acceleration of body. |
