| 摘 要： | 针对某重型车辆油气混合型悬架试验系统,建立了油气悬架负载的电液伺服驱动力控制系统的数学模型,并分析了负载刚度变化对系统幅值裕量与相位裕量的影响,得到控制参数与负载刚度之间的关系.为了能够提高系统的动态性能,引入根据刚度变化自动进行增益和转折频率调整的二阶校正环节.仿真和试验均表明所提方法对提高试验精度的有效性.

| Abstract: | A mathematic model of electro-hydraulic servo driving force control system for a heavy vehicle hydro-pneumatic suspension was established.Through analyzing the influence of the varying stiffness of hydro-pneumatic suspension to amplitude margin and phase margin,a relationship between stiffness of the load and controller parameters was obtained.In order to improve the dynamic performance of the hydro-pneumatic suspension testing system,a two-stage correction segment was introduced which can change its gain a... |
