现代先进飞机配置多个操纵面且又冗余,这有利于实现非常规飞行,提高飞机敏捷性,使飞机在机动和故障时有更多的选择,但是同时也导致了飞机控制设计复杂度的增加.为了达到更好的效果,就必须利用控制分配器来充分利用多操纵面的不同带宽.从频率域角度出发,研究了动态控制分配方法,并将其应用于某型先进战斗机的控制分配器设计中,利用鸭翼的频率特性抵消府舱过载,经仿真验证,采用动态控制分配策略时,可以有效地减小座舱过载,同时还可以减小配平阻力,取得了良好的控制效果.

A scheme named dynamic control allocation is introduced in this paper as a mean of the design of fighter with multi-effectors' flight control system. Contrasts to the existing control allocation schemes that only consider in the magnitude domain, this solution affect the distribution of the control effect both in the magnitude domain and in the frequency domain. It is proved that this scheme can make full use of different actuator bandwidth and get the outstanding features (counteract the pilot load factor and minish the trimmed drag) according to the digital simulation of a modern fighter model with multi-effectors.
