摘要/Abstract

摘要： 基于模态直接切换的飞行高度控制方法,在输入控制指令后,存在控制量输出震荡,甚至发散的问题。幂函数符合飞行高度指令变化规律,以此为原型函数,推导给定高度,当前高度和垂直速度之间的关系,将这一变换关系作为垂直速度控制回路的输入指令,设计了平稳控制系统,该系统不需要进行控制模态切换,就可以实现飞行高度保持,以及飞行高度的改变。通过A320飞行仿真平台对设计的平稳控制系统进行性能分析,结果表明该系统可以实现高度的平稳控制,且稳态误差得到了很好抑制。

Abstract: Based on the fly height control method of modal direct switching, after the input of the control command, the control output may be oscillated or even diverged. The power function conforms to the variation law of the flight altitude command, and is used as the prototype function to derive the relationship between the given height, the current height and the vertical velocity. Using this transformation relationship as the input command of the vertical velocity control loop, a smooth control system is designed. The system does not require control modal switching and can achieve the flight altitude maintenance andflight altitude change. The performance analysis of the designed smooth control system is carried out by the A320 flight simulation platform. The results show that the system can achieve a high degree of smooth control and the steady-state error is well suppressed.

Key words: vertical speed control, altitude control, power prototype function, A320 flight simulation
