摘要:
针对空间碎片清理问题,提出了一种利用航天器与空间碎片混合编队队形重构控制技术捕获碎片的方法。首先,分析了地/月—日系L2拉格朗日平动点附近的限制性三体环境,并建立了编队卫星相对运动动力学模型;其次,提出了以太阳光压力作为航天器与空间碎片编队队形重构的控制力,实现各从星接近空间碎片的目的;最后,设计了基于线性二次型的最优控制器,并在Matlab/Simulink环境下进行仿真实验。仿真结果表明该方法可控制从星到达期望的位置(空间碎片的位置),且太阳帆板的姿态变化在可控范围内,进而证明了该方案可以应用于复杂空间环境下的碎片清理任务。

Abstract:
In order to solve debris removal problem, a capture method of mixed formation of spacecraft and space debris is proposed. Firstly, the restricted three-body circumstance near the L2 point of Earth/Moon-Sun is analyzed and the relative dynamics model of formation satellites is established. Then, a control strategy, using sunlight pressure as the spacecraft and debris formation reconfiguration force, is proposed so that achieving the purpose of approaching debris by follower satellites. Lastly, a linear quadratic optimal controller is designed and simulated by Matlab/Simulink. The results show that the method can help control followers achieve the target track (location of space debris), while the change of the solar sail attitude is kept under control. Therefore, it proves that the method can applied to the debris removal problem in complex space environment.
