Separation and reconfiguration of stacked satellites in orbit is an effective method for constructing large space structures. This paper investigates the dynamics of a stacked satellite system (SSS) during the separation and reconfiguration process. Firstly, the dynamic model of the SSS is established via the natural coordinate formulation (NCF) to conveniently handle the time-varying constraints between satellites. Then, the separation and reconfiguration strategies are proposed for the SSS including the reconstruction step between two configurations. To ensure collision-free satellite assembly, a proportional differential (PD) controller combined with a potential function is introduced. Additionally, a docking mechanism is designed, considering collision force constraints during satellite docking assembly. Finally, several numerical simulations are conducted to demonstrate the effectiveness of the separation and assembly strategies.

堆叠卫星系统的重构和组装动力学

在轨堆叠卫星的分离与重构是构建大型空间结构的有效方法。本文研究了堆叠卫星系统（SSS）在分离和重新配置过程中的动力学。首先，通过自然坐标公式（NCF）建立SSS的动力学模型，以方便处理卫星之间的时变约束。然后，提出了 SSS 的分离和重构策略，包括两种配置之间的重构步骤。为了确保卫星组装无碰撞，引入了与势函数相结合的比例微分（PD）控制器。此外，考虑卫星对接组装过程中的碰撞力约束，设计了对接机构。最后，进行了几次数值模拟来证明分离和组装策略的有效性。
