摘要：
电磁编队飞行（EMFF）利用电磁力来控制多个卫星之间的相对位置，而无需使用传统的基于燃料的推进系统。为了补偿伴随电磁力产生的电磁扭矩，在大多数先前研究中，除了电磁线圈外，所有卫星都被假设配备了反应轮（RWs）。然而，由于电磁扭矩通常在卫星之间不同，带有RW的角动量会非均匀地分布在卫星之间。如果没有适当的控制方案，这种偏差会随时间增加，导致RWs迅速饱和，从而阻碍卫星姿态的控制。在本研究中，提出了一种新的控制器，能够同时控制电磁力和扭矩。基于角动量守恒的EMFF运动学用于控制器设计。该控制器可以在不使RWs饱和的情况下控制n个卫星，并且所有卫星中只需要一组RWs。所提出的控制器与专属于主卫星的简单卸载控制相结合，从而消除了整个系统中角动量的积累。通过五卫星系统的编队维护和编队重构的数值模拟，证明了所提控制器的有效性。
英文摘要：
Electromagnetic formation flight (EMFF) uses the electromagnetic force to control the relative positions of multiple satellites without using conventional fuel-based propulsion. To compensate for the electromagnetic torque generated alongside the electromagnetic force, in most previous studies, all satellites were assumed to have reaction wheels (RWs) besides electromagnetic coils. However, the RW-loaded angular momentum becomes non-uniformly distributed among the satellites, because the electromagnetic torque usually differs between satellites. Without a proper control scheme, this deviation increases over time, and the RWs become saturated quickly, preventing the attitudes of the satellites from being controlled. In this study, a new controller is proposed that enables the electromagnetic force and torque to be controlled simultaneously. The EMFF kinematics derived from the conservation of angular momentum are used for the controller design. This controller can control $n$ satellites without saturating the RWs, and only one set of RWs is required among all satellites. The combination of the proposed controller with a simple unloading control exclusive to the chief satellite results in the elimination of the accumulation of angular momentum in the entire system. The effectiveness of the proposed controller is demonstrated through numerical simulations of the formation maintenance and formation reconfiguration of a five-satellite system.
