中文摘要： 本项目主要研究针对空间非合作目标的交会和逼近控制问题，核心是引入面向对象特征与控制目标的特征建模方法，实现针对非合作目标的优化、精确、安全可靠的交会和逼近控制。具体内容包括：针对非合作目标的交会和逼近相对运动的特征建模；基于特征模型的非合作目标交会控制；基于特征模型的非合作目标逼近控制。通过本项目的研究，期望给出针对非合作目标相对运动的系统化特征建模方法，解决椭圆轨道最优脉冲交会问题、基于特征模型的最优交会轨迹跟踪控制问题和综合考虑安全性、挠性振动、相对动力学不确定、相对姿态和位置耦合等因素的非合作目标逼近控制问题。为近程导引段和最后逼近段的非合作目标的交会和逼近提供系统化的可行、可靠的解决方案。

英文摘要： This project mainly studies the control problem of rendezvous and approach to non-cooperative target in space. In order to achieve optimal, accurate, safe and reliable control of rendezvous and approach, we introduce control based on method of characteristic modeling which considers both dynamic characteristics of control object and control target. The specific studies are as follows: characteristic modeling for rendezvous and approach to non-cooperative target in space, rendezvous control for non-cooperative target based on characteristic modeling and approach control for non-cooperative target based on characteristic modeling. The aims of this project are: to give systematic method of characteristic modeling for relative motion between chasing spacecraft and non-cooperative target, to solve the problems of optimal multi-impulse rendezvous in an elliptical orbit, optimal trajectory tracking control based on characteristic modeling and approach control for non-cooperative target based on characteristic modeling considering safety, flexible vibration, uncertainty of relative dynamic model and coupling relative position and attitude dynamic model. Finally, an applicable and reliable solution will be given for rendezvous and approach to non-cooperative target in both close range phase and final approach phase.
