基于鲁棒协同控制方法的多航天器交会问题

Robust Coordination Control for Multi-Spacecraft Rendezvous Problems

  • 摘要: 提出一种解决多航天器交会问题的协同控制算法。首先应用图论中邻接矩阵及拉普拉斯矩阵的定义及其相关性质,描述了多航天器之间的通信拓扑关系;其次对目标航天器轨道为椭圆形情况下的交会问题进行构建,并设计了相应的协同控制算法;最后利用李雅普诺夫函数证明该系统的稳定性,并且能够保证消耗的能量最优以及最大推力受限。仿真实验表明:提出的方法可以实现多航天器的协同交会,验证了该方法的有效性。

     

    Abstract: This paper proposes a coordination controller for the multi-spacecraft rendezvous problems. The communication topology among multiple spacecraft is firstly described with the help of adjacency matrix properties by using the graph theory. Then the problem of multi-spacecraft rendezvous under the case that the orbit of target spacecraft is ellipse has been described, and the coordination controller is designed. Finally, the stability of system has been proved by applying the Lyapunov function method, further, the energy cost is optimized and the maximum control force is constrained. The simulation example illustrates the effectiveness of the theoretical results and shows that the proposed coordination controller can achieve the multi-spacecraft rendezvous.
