分别采用常规动态逆和模型参考动态逆设计了战斗机飞行控制律,并通过开环时域仿真以及基于任务的闭环飞行品质评估方法,对比分析了两类控制律的特点及差异。研究表明,模型参考动态逆对高频小幅指令跟踪效果较好,在需要驾驶员频繁补偿的飞行任务中表现出的飞行品质更佳。研究结果对战斗机飞行控制律的选择与设计、控制律与飞行任务种类的匹配有一定的参考意义。
The fighter flight control law is designed by using the conventional dynamic inverse and the model reference dynamic inverse. The open-loop time-domain simulation and the task-based closed-loop flight quality assessment are used to analyze the characteristics and differences of the two types of control law. The research shows that the model reference dynamic inversion has a good effect on high-frequency and small-amplitude command tracking, and shows better flight quality in missions that require frequent driver compensation. The results of the research have certain reference meaning for the selection and design of fighter flight control law and the matching of control law and flight mission types.
