【摘要】 本论文研究的内容来自于兴平华兴公司航空机轮刹车试验台的第二期技术改造项目。主要研究实验台液压系统的计算机控制系统设计实现问题。研究的重点是位置和载荷控制两个部分。 论文首先介绍二期改造系统设计方案,包括系统的选型、计算机网络的连接和硬件的配置。随后采用理论分析与系统辨识的方法建立了位置控制系统与载荷控制系统的数学模型,在此基础上针对系统设计了PID控制器,给出PID的控制参数,其次针对载荷控制系统的数学模型参数变化、干扰较大的情况,应用H?鲁棒控制理论设计出载荷鲁棒控制器,仿真结果比较表明,鲁棒控制的效果优于PID控制。为验证所设计控制器的效果,建立了半实物仿真系统,对位置控制系统与载荷控制系统进行了检验。结果表明本论文建立的系统数学模型是合理的,控制器满足系统要求。

【Abstract】 This thesis is derived from the second stage of the technical improvement project of the Aircraft Tyre Wheel and Brake Test Dynamometer which focuses on the design and realization of the computer control system. The main effort of this paper is on the design of position control and load control.Firstly, the thesis finished the design of the second stage of technical improvement scheme,including selection of control system, connection of network and hardware configuration.Next,the mathematical model of Position&Load control system is obtained from the theory analysis and system identification, Then the classical PID control scheme are applied to this model and the parameters and simulations of classical PID control are given as the result. Considering the variety of the model parameters and great disturbance .the H-infinity controller is used, the result indicates that the H-infinity controller is better than the PID controller. The semi-physical simulation system is established to test the position and load control system, the results show that the established mathematical model is reasonable and the controller meet the demand of the whole system design.
