摘要:

针对利用多星编队协同绕飞空间非合作目标的控制问题,考虑外部干扰和目标非期望轨道机动影响,提出了一种基于全驱系统理论的分布式约定时间预设性能控制方法。首先,基于视线坐标系建立服务航天器编队绕飞非合作目标的相对运动方程,并将其转化为全驱系统形式以降低控制器设计复杂度;其次,结合拓扑理论设计一种分布式约定时间预设性能控制器,保证多星编队绕飞的瞬态和稳态控制性能;此外,引入扩张状态观测器观测并合理补偿系统中存在的不确定项与干扰,提高多星编队绕飞的控制精度与鲁棒性。最后,通过两组绕飞仿真验证了所设计控制方法的有效性。

Abstract:

To address the cooperative control problem of using spacecraft formation for approaching and flying around the non-cooperative target, a distributed prescribed performance control method based on the fully-actuated system theory is proposed in consideration of external interference and unexpected orbital maneuvers. First, a relative dynamic model for the service spacecraft formation and the non-cooperative target is established based on the line-of-sight coordinate system, and the fully-actuated control law is constructed to reduce the complexity of controller design. Furthermore, a distributed agreed-time prescribed performance controller is designed using the topology theory to ensure the control performance of the spacecraft formation around the target. In addition, an extended state observer is employed to observe and compensate for the uncertainties and disturbances in the system, thereby improving the control precision and robustness in spacecraft formation flying around the target. Finally, the effectiveness of the designed control method is verified by two sets of flying around simulations.

Key words: fully-actuated system theory, formation flying-around, non-cooperative, prescribed performance control, extended state observer
