针对空间操控的任务需求,以高轨航天器轨道延寿为背景,分析了飞行任务流程。重点对超近距离段的相对姿态、相对轨道耦合动力学进行了分析和建模,设计了姿轨耦合控制律。同时,针对高轨卫星对天面安装有远地点发动机的特征,设计了非合作目标图像特征识别、提取和相对测量算法。最后通过搭建分布式仿真系统,结合小型对接捕获机构,对超近距离的相对导航和相对运动控制进行了地面仿真试验,校验了对高轨航天器的远地点发动机喷管进行捕获从而实施在轨延寿的可行性。
In view of the mission requirements of space control, the flight mission process is analyzed on the basis of the orbit longevity of high-altitude orbit spacecraft. The relative attitude and relative orbit coupling dynamics of the super-close-range segment are analyzed and modeled, and the attitude-rail coupled control law is designed. In the meantime, aiming at the characteristics of high altitude orbit satellites installed on the surface of the sky with apogee engines, the non-cooperative target image feature recognition, extraction and relative measurement algorithm are designed. Finally, by building a distributed simulation system and combining with a small docking and catching mechanism, ground-based simulation experiments of relative navigation and relative motion control at very close range were performed to verify whether the orbital locomotive nozzle of a high-orbit spacecraft was captured to perform on-orbit Life extension of the feasibility.
