摘要: 采用定量反馈理论,可以设计具有参数不确定性的飞行仿真转台的鲁棒控制系统.分析和总结了定量反馈理论的基本原理和设计过程.采用QFT设计了某型飞行仿真转台的反馈控制器和前置滤波器,组成了转台的控制系统.实验结果表明,当转台的负载发生变化时,系统仍然能够保持良好的跟踪性能.这证明了系统的鲁棒性.此外,与PID控制的对比表明,QFT控制能够克服摩擦非线性,具有良好的抗干扰性能.QFT在飞行仿真转台上的成功应用说明了该方法具有工程实用价值.

Abstract:  To design the robust control system for flight simulator with large parameter uncertainty, quantitative feedback theory (QFT) was employed. The principle and design process of QFT were presented. The feedback controller and prefilter were designed using QFT, which make up of the control system of a certain flight simulator. The experiment result shows that the system keeps up perfect tracking performance when the loads of the flight simulator are changed. It indicates robustness of the system. The comparison with PID control demonstrates that QFT control is able to reject the friction nonlinearity. The anti-disturbance ability of QFT is very good. The application to flight simulator of QFT is successful. It shows the engineering value of the control method.
