英文摘要： For a team of spacecafts cooperatively achieving the approaching, surveillance, berthing and maintenance to a non-cooperative target on orbit, a higher requirement on self-control, precision and reliability is emerged for formation flying. The formation configuration, trajectory planning and control is researched in this project for the surveillance and maintenance of the non-cooperative target. The main contributions of this project are as follows: 1) Design time-fuel optimal, heterogeneous and multi-dimensional formation flying configuration for servicing spacecrafts and a common non-cooperative target; 2) Establish the system-level integration of attitude and orbit coupling dynamics, which can accurately reflect the attitude /orbit coupling relations for a couple of servicing spacecrafts and the formation dynamics feature; 3) Propose the optimal relative transition trajectory planning for the formation flying ,which can consume minimum fuel at the formation initialization stage and minimize the time-fuel at the formation reconfiguration stage; 4) Present the robust control algorithm for the maintenance configuration to achieve the precision and stability control of servicing spacecraft's attitude and orbit. The research of the project put forward the key approach to realize the cooperative maintenance of non-cooperative targets using a team of spacescraft.
