| 摘 要： | 建立了履带车辆二自由度车体振动模型，选定状态变量，得出悬挂系统状态方程和振动微分方程。提出了基于线性二次型（LQR）最优控制理论的半主动控制算法。对硬土路面激励下履带车辆悬挂系统的半主动控制效果进行了仿真，并与被动控制效果进行比较。结果表明该算法能很好控制车体位移和加速度。

| Abstract: | Vibration model with 2D of freedom of vehicle was established. The state equation and vibration differential equation of suspension system was set up through selecting state variable. In the light of LQR optimal algorithm, a semi-active control strategy was presented. The effects of vibration control with the sand road excitation were simulated, and compared with the effects based on passive control. The result shows that displacement and acceleration of the track vehicle are reduced greatly. |
