Capturing large space debris with complex rotational motion is extremely challenging. A de-tumbling phase before capturing may be necessary to reduce the risk of collision with debris. This paper proposes a new noncontact de-tumbling method using a two-satellite electromagnetic formation, in which two small electromagnetic satellites, each having a high-temperature superconducting coil, generate control torques to reduce the rotation rate of debris prior to making any physical contact. The electromagnetic interaction of the target-satellite system is analyzed. A relative translational dynamics of the target–satellite system and the attitude dynamics of the target are established. Simulation results show that the proposed method effectively eliminates the rotational motion of the target. It can be safely concluded that the noncontact method for de-tumbling space debris using a two-satellite electromagnetic formation is feasible and potentially applicable to on-orbit capture.

用复杂的旋转运动捕获大空间碎片极具挑战性。在捕获之前需要进行脱粒阶段，以减少与碎屑碰撞的风险。本文提出了一种新的非接触式解扰方法，该方法采用了两颗卫星的电磁结构，其中两颗分别具有高温超导线圈的小型电磁卫星在产生任何物理接触之前会产生控制转矩以减小碎片的旋转速率。 。分析了目标卫星系统的电磁相互作用。建立了目标-卫星系统的相对平移动力学和目标的姿态动力学。仿真结果表明，该方法有效地消除了目标的旋转运动。
