摘要

摘要: 针对现代战斗机大迎角机动的飞行控制设计问题，在角速率指令非线性动态逆控制律基础上，引入表征期望飞行品质的理想参考模型，构成了模型参考动态逆飞行控制律，并借助基于任务的飞行品质评定方法完成了控制参数的整定，从而实现了对飞机大迎角机动的控制.对设计结果进行了时域和频域仿真，并使用基于任务的飞行品质评定方法对闭环系统的飞行品质进行了评定，验证了控制律设计的有效性.通过不同任务下评定结果的对比，说明了这一方法在揭示飞机大迎角飞行品质特性和特定任务对飞行控制律的特殊要求这两方面的优越性，可用于战斗机大迎角机动的非线性飞行控制律设计与飞行品质的评定.

Abstract: To solve the problem of maneuver control for fighters at high angle-of-attack (AOA), the model reference dynamic inversion (MRDI) control law was designed, based on the nonlinear dynamic inversion controllers utilizing angular rates as commands, ideal reference models representing the desired flying qualities and proportional-plus-integral compensators. Both the expected type of vehicle response and the control of maneuver at high AOA were approached by this method. The tuning of controller parameters, the rating of the airplane performance and the evaluation of close-loop system flying qualities were completed by simulation and the mission-oriented flying qualities (MOFQ) method which could be considered as a feasible assessment method for flying qualities at high angle-of-attack and it pointed out the demands for flying qualities created by special missions. The MRDI control law and the MOFQ method can be referenced by fighter control law design and flying qualities evaluation.
