摘　　要：利用动态逆反馈控制方法设计的飞行控制器,依据动态解耦的特性,可以完成常规操纵的同时,借助辅助舵面,利用控制分配技术实现特定飞行操纵。本文主要研究动态逆反馈控制框架下与直接升力控制相匹配的控制分配技术,提出了两种控制分配结构,分别通过几种常用控制分配算法的仿真分析,结果显示在航迹回路与姿态回路分别设计控制分配结构,与动态逆反馈控制框架下的直接升力控制匹配性更好,舵面响应特性显著改善。同时表明在动态逆反馈控制框架要实现类似利用直接升力操纵航迹,对直接升力面、推力等辅助执行机构的控制分配应在航迹回路直接实现。According to the characteristics of dynamic decoupling,the flight controller designed by the dynamic inversion feedback control method can accomplish the conventional control.At the same time,with the aid of the auxiliary control surfaces,the control allocation technology can be used to realize the specific flight manoeuvring.This paper mainly studies the control allocation technology matching with the direct lift control in the dynamic inversion feedback control framework and proposes two control allocation structures.The simulation analysis on several common control allocation algorithms shows that the control allocation structure is designed separately in the trajectory tracking and attitude loops.The direct lift control is better in matching with the dynamic inversion feedback control framework.The response characteristics of the control surfaces have been significantly improved.At the same time,it shows that in the dynamic inversion feedback control framework,the control allocation of the auxiliary Actuators,like direct lift surface or thrust,should be realized directly in the track loop.
