本发明提出一种兼顾时效性和燃料最优的卫星集群协同迁移重构方法。所述方法首先,建立了考虑多种空间摄动的星群相对运动模型。随后,针对星群中的主星,提出了一种改进粒子群算法的时间最优轨迹规划方法,实现主星的快速迁移。进而,针对其余成员卫星设计了一种结合鲁棒模型预测控制和蜂拥控制的协同控制器,使从星能够快速协同的跟随主星到达任务指定的区域。最终,通过仿真实验,验证了控制策略的有效性,为星群的自主协同重构提供了一种有效的解决方案。

    The invention provides a satellite cluster collaborative migration reconstruction method considering timeliness and fuel optimization. The method comprises the following steps: firstly, establishing a satellite group relative motion model considering various spatial perturbation; then, for a primary satellite in the satellite group, a time optimal trajectory planning method of an improved particle swarm algorithm is provided, and rapid migration of the primary satellite is realized. Furthermore, a cooperative controller combining robust model predictive control and swarming control is designed for other member satellites, so that the slave satellites can quickly and cooperatively follow the master satellite to arrive at a region specified by a task. Finally, the effectiveness of the control strategy is verified through a simulation experiment, and an effective solution is provided for autonomous collaborative reconstruction of the satellite group.
