中文摘要： 面向快速响应空间的集群航天器是未来航天器系统空间应用的一种新理念和新方向，它的出现将对空间技术和航天产业带来革命性的影响。本项目针对集群航天器中数量总多的功能模块航天器近距离集群飞行，相对轨道构形松散且主要依靠被动稳定，相对控制采用内部势场力且相互耦合严重的问题，将剖析基于电磁力/库伦力共享控制的集群航天器相对动力学机理并建立相应的动态特性模型，突破长期被动稳定/自由飞行松散队形等多约束条件下的构形优化配置方法，从共享控制力的时变/时滞特性角度出发，开展集群构形的稳定性分析并提出基于控制力动态耦合的集群构形协调控制算法，通过数学仿真验证相关方法的有效性，为未来集群航天器的空间示范应用提供理论基础。

英文摘要： The spacecraft cluster for the rapid response space is a latest concept and directions for space applications of future spacecraft systems. And, there will be a revolutionary impact on space technology and aerospace industry due to the emergence of spacecraft cluster. Aimed at the multiple functional modules spacecraft free-flying, the passive stability of loose configuration and relative state control by serious coupled internal potential field force, the shared control mechanism based on the electromagnetic force / Coulomb force will be analyzed and the relative dynamic characteristics model will be established. And the configurations optimized design method with constraints of the long-term passive stability / free-flying loose formation is put forward. From the point of time-varying/delay of shared control force, the stability analysis of the spacecraft cluster is carried out and the cluster coordinated control algorithm is proposed. Finally, the effectiveness of the relevant methods can be verified through mathematical simulation. It will provide the theoretical basis for future application of spacecraft cluster.
