摘要
本文研究最佳状态反馈液压伺服系统的模型、设计方法、仿真和试验结果。被控的伺服机构用一个5阶的状态方程和不同的输出方程来描述,采用CAD技术计算最佳反馈系数。作为一个例子我们研究了一个用本文所提出的方法构造的液压伺服振动台,研究的结果表明,最佳状态反馈的液压伺服系统的动态性能大大优越于非最佳反馈系统。
This paper deals with the model, method of design, simulation and experimental results of optimalstate feedback hydtaulic servosystems. The controlled servomechanism is described by 5-dimensionstate equation and different output equations. The technique for the CAD has been developed tocompute the optimal feedback factors. As an example a system of hydraulic servo vibrator whichis constituted according to the technique in the present paper has been studied. It has been shownthat the dynamic behaviour of the optimal feedback hydraulic servosystem is much better than thatof non-optimal feedback systems.
