| 摘 要： | 飞机进场着陆是飞机飞行的关键阶段,由于飞机和外界条件存在许多不确定因素,对飞机着陆精度和安全性有很大影响。QFT是在相频平面上的一种图形化的鲁棒控制系统设计方法。采用QFT理论设计了某型飞机的纵向着陆控制律,并应用了推力综合控制稳定飞机下滑时的速度。仿真结果显示,飞机着陆实现了对期望着陆轨迹的精确跟踪,满足了着陆控制的要求。

| Abstract: | Quantitative Feedback Theory(QFT),is a frequency-domain-based robust control design approach that was developed in the early 1970s and has received considerable attention over the past two decades.In the last few years,its application to aircraft flight control systems design has been widely investigated.In this paper a longitudinal robust automatic landing control law was designed by QFT approach combine with thrust controls.The simulation results shows with this control law the plan landing smooth and safely. |
