摘要:

从巨型星座在自然摄动下轨道运动的力学特性出发,分析了星座构型保持的任务特点。针对轨道面内由大气阻力和面质比差异导致的轨道面内长期相对运动,构造了星座相对构型保持的二阶一致性控制方法。针对星座多个体系统不同的星间链路连接情况和闭环网络特征,提出了不同几何拓扑结构及其相应的图论构造方法。相较于经典的绝对位置保持方法,相对构型保持只需补偿面质比差异造成的构型漂移变化,因此能够以更小的控制代价实现星座的构型保持。以星型链路的拓扑结构为例,进行了星座相对构型保持的仿真分析,离散一致性控制能够实现星座构型长期稳定。

Abstract:

In this paper, maintenance of huge constellation configuration with orbit perturbation is studied in terms of motion characteristics. Considering the in-plane relative motion caused by air drag and different area-mass ratios, a second order consensus control method is proposed for constellation relative-configuration maintenance. Considering the connection situation of inter-satellite links and the characteristics of close-loop network, a construction method of the graph theory for different topologies is developed. Compared to the classical absolute position maintenance of constellation, the relative configuration maintenance method only needs to reduce the configuration excursion caused by different mass-area ratios. Therefore, the relative configuration maintenance method is more effective in energy saving. Then, simulation of relative-configuration maintenance in star structure constellation is conducted. The simulation results show that relative-configuration maintenance can achieve long-term stability of a constellation configuration.

Key words: constellation, relative-configuration maintenance, inter-satellite link, graph theory, second order consensus control, topology structure
