| 摘 要： | 一、引言 在垂风干扰作用下,常规飞机往往不能保持航迹角不变,从而使得航迹变化越来越大,这在很多情况下是不符合飞机飞行要求的。而直接升力控制系统,由于实现了对应状态的解耦,在垂风干扰作用下,则可以基本保持航迹角不变。如果采用抗干扰调节器设计方法设计直接升力控制系统,则可以始终保持航迹角为0,从而保证航迹不变。本文以某型飞机为背景讨论了上述问题。采用离散域直接设计。

| Abstract: | This paper discusses the conventional aircrafts and their control systems against vertical gust. Then, the design of direct lift control systems against vertical gust is introduced in which the state feedback control is used for eigenstructure assignment in discrete time domain. The airplane with the controller could effectively alleviate the disturbance of vertical gust. |
