集群航天器球形边界控制

集群航天器由于其独特的优势，在未来航天任务中将举足轻重，其边界控制也随即成为研究热点.针对近距离伴飞的圆轨道集群航天器，以集群航天器蜂拥控制模型为基础，通过集群航天器球形边界的定义，运用粒子群优化算法，实现了稳定状态下集群航天器的边界参数寻优.采用球形空腔势函数的控制方法，结合集群航天器边界参数反馈信息，实现了对集群航天器球形边界控制，并仿真验证了算法的可行性.

Spherical Boundary Control of Cluster Spacecraft

The cluster spacecraft will play an important role in future space missions due to its unique advantages, and its boundary control becomes a hot spot for research. In this paper, based on the cluster spacecraft’s swarm control model，the particle swarm optimization algorithm is used to acquire the boundary parameters(the minimum envelope radius and the spherical coordinates) of the cluster spacecraft when the state are stable. At the same time, the control method of the spherical cavity potential function is proposed. Combined with the feedback information of the boundary parameters of the cluster spacecraft, the spherical boundary control of the cluster spacecraft is realized. The feasibility of the algorithm is verified by simulation.
