文中研究了用于飞机发动机地面模拟台的大功率电液速度伺服控制系统的控制方法.为使系统达到快的响应特性,应用计算机控制手段,采用最少拍控制结合模糊控制的方法.在实验和理论分析的基础上,建立了简化的一阶环节模型和二阶环节模型,分别设计了最少拍控制器,并进行了控制实验.实验结果表明,应用二阶环节模型进行最少拍控制并结合模糊控制,可获得满意的响应特性.
In this paper, the control method of high-power electro-hydraulic speed servo control system for aircraft engine ground analogue platform is studied.In order to make the system achieve fast response characteristics, the computer control method and the least shot control combined with fuzzy control method are used.In the experiment and Based on the theoretical analysis, a simplified first-order model and a second-order model are established, the least-shot controller and the control experiment are designed respectively. The experimental results show that the second- Control, you can get a satisfactory response characteristics.
