摘要: 建立了伺服方向阀构成的液压主动悬架系统的单轮数学模型,将系统最优控制问题归结到标准LQG问题后,通过仿真,得出了在有诸多约束的情况下,用普通的液压伺服系统也能得到较好的振动控制效果的结论,并对全状态反馈控制与输出反馈控制进行了讨论。

Abstract: A single-wheel mathematical model of hydraulic active suspension system composed of servo directional valve is set up. After the optimum control problem is transferred to standard LQG problem, simulation is performed to show that the hydraulic servo system, within several restrictions, can produce a satisfactory effect on vibration control. The all - state feedback control and output feedback control are also discussed.

Key words: Active control, Hydraulic servo system, LQG problem, Stochastic control
