大迎角自动进近短距着陆综合控制设计及仿真研究

飞机在大迎角下进近可以减小飞机进近着陆的速度,从而减小飞机着陆时的滑跑距离。本文根据国外大迎角短距着陆的研究1,2]给出了一种大迎角自动短距着陆方案。该方案应用了飞行与推进协调控制的方法设计了自动着陆控制系统和一套控制律,实现了进近飞行时的低速稳定和精确的航迹控制。对于反旋机动,利用全状态反馈,实现了机尾高度的精确控制。仿真结果表明该方案切实可行。

Research of Integrated Flight and Propulsion Control Design and Simulation for High Angle of Attack Autonomous Approach and Landing

Approach at high angles of attack allows greatly reduced touchdown speed that results in much shorter landing distances. According to foreign researches on the high angle of attack approach andshort landing, animprovedscheme of high angle of attackautonomous short landing is presented. The scheme adopts the method of Integrated Flight and Propulsion Controlto design an autonomous landing control system and a set of control laws which fulfill the stableand accurate trajectory trackingat a low approach speed. In the de-rotation maneuver, the tail clearance is accurately controlled using full state feedback. The simulationresults show that the scheme is feasible.
