| 摘 要： | 建立悬架系统和电液伺服作动器数学模型,分别在正弦信号激励和随机路面激励下,设计最优控制器,在MATLAB/simulink里搭建仿真模型进行数值仿真。仿真结果表明:最优控制的电液主动悬架系统对由路面输入引起的振动能有效抑制,车身加速度、悬架动挠度和轮胎动载荷与被动悬架相比分别降低20%~55%、25%~44%、0%~54%,车辆行驶平顺性和操纵稳定性得到很大改善,验证了控制器的性能。

| Abstract: | Build the model of active suspension and electro-hydraulic servo actuator. Under random road surface and sinusoidal signal,design the optimal controller and build simulation system in the software of MATLAB/simulink. Simulation results showed that the electro-hy- draulic active suspension system with a optimal controller can effectively reduce the vibrations caused by road excitation, and there was 20% to 55%,25% to 44%,0% to 54% reduction in acceleration, dynamic deflection and dynamic load compared to the passive suspension, apparently improved the ride smoothness and vehicle handling.Simulation is verified the performance of the proposed controller. |
