| 摘 要： | 通过建立1／4车辆模型和路面输入模型，应用耗散系统理论进行了车辆主动悬架严格（Q，S，R）-耗散状态反馈控制器的设计，并在Matlab／Simulink环境中建立系统模型并进行仿真研究，将主、被动悬架的车身加速度、悬架动行程和轮胎动位移3项指标进行了对比分析。仿真结果表明，具有严格耗散控制器的主动悬架对车辆乘坐舒适性和行驶平顺性的改善有良好的效果。

| Abstract: | A 1/4 car model and a road input model were established based on the dissipative system theory which was used to design a strictly（ Q ,S ,R） - dissipative state feedback controller of automobile active suspension. A system simulation based on Matlab/Simulink environment was built up and used for simulation.Three performance indexes, body acceleration, suspension dynamic travel and tire dynamic deflection were compared. The simulation results indicated that the active suspension with a dissipative controller could improve automobile riding comfort performance enormously. |
