| 摘 要： | 阐述了定量反馈理论(QFT)的基本原理及设计方法,并给出了某型飞行仿真转台的QFT控制器设计实例。为了有效地抑制高频测量噪声对系统的干扰,以及避免系统的高频不确定性,在单环QFT控制的基础上,引入了基于多环QFT的鲁棒控制。理论分析和仿真实验表明,这种多环QFT控制可以明显地缩减控制器的带宽,使系统具有很强的抗高频测量噪声的性能,达到了理想的控制效果。该方法在转台的控制上取得了成功的应用,具有广泛的应用价值。

| Abstract: | The principle and design process of QFT is presented. As a sample, the design of QFT controllers for a flight simulator is given. To reject the distrubance of high-frequency sensor noise in controll system, multi-loop QFT is introduced for robust control on the base of single-loop QFT. A simulation shows that this method is able to reduce the bandwidth of controller effectively and realize perfect controll. The design methodology is succefully applied to flight simulator .which shows it is very valuable to practical control system. |
