新太空时代的到来使近地轨道（LEO）卫星数量迅速增长，为此近期出台了更严格的离轨要求以避免LEO出现凯斯勒综合征，这推动了空间碎片清除新概念的提出，其中将立方卫星（CubeSat）附着于空间碎片作为一种有前景的缓解策略。该策略的初始阶段是稳定并控制碎片的姿态，本文提出一种采用附着式带分级离子电喷推进器（iESE）的立方卫星对退役卫星进行姿态控制的设计，iESE的紧凑设计结合分级结构可提升可靠性与任务时长。组合系统（卫星与附着式立方卫星）的动力学存在较大不确定性，对控制设计构成重大挑战，本文采用鲁棒控制框架中的μ综合方法应对该挑战，并在带有多个柔性附件的退役卫星上验证了该方法的可行性。
英文摘要
The emergence of the New Space era has led to a rapidly increasing number of satellites in Low Earth Orbit (LEO). Consequently, more stringent deorbiting requirements have recently been imposed to avoid the Kessler syndrome in LEO. This has resulted in the proposal of new concepts for space debris removal, including attaching CubeSats to space debris as a promising mitigation strategy. The initial phase of this strategy involves stabilizing and controlling the debris' attitude. This paper proposes an attitude control design for decommissioned satellites using attached CubeSats with staged ion electrospray engines (iESE). The compact design of iESE combined with staging provides increased reliability and mission durations. The large uncertainty in the dynamics of the combined system, i.e. satellite and attached CubeSats, poses a significant challenge to the control design. The approach taken here uses the robust control framework, specifically $μ$-synthesis, to tackle this challenge. The feasibility of the approach is demonstrated on a decommissioned satellite with multiple flexile appendages.
