摘　　要：基于多智能体系统一致性理论,在有向拓扑结构中对模块化航天器相对轨道的队形控制问题进行研究.考虑与状态相关的未知外部干扰,在存在模块质量不确定性的情形下,基于自适应增益技术,设计仅依赖模块自身及其邻近模块信息的分布式控制算法,并通过Lyapunov稳定性方法证明闭环系统是渐近稳定的.最后在Matlab/Simulink中对6个模块组成的模块化航天器系统的队形进行仿真分析,仿真结果表明所设计的控制律是有效且可行的.The formation control problem for relative translation of the modular spacecraft is studied under a directed graph based on the consensus theory of multi-agent systems. The disturbances on the modules are unknown and associated with the module states. Based on the adaptive gain design, a distributed control algorithm is proposed under the condition that the modules’ masses are unknown. And the closed-loop system is proved to be asymptotically stable via the Lyapunov method. Simulation results of a scenario of six modules are provided to show the effectiveness of the proposed control schemes.
