基于椭圆空腔虚拟势场的航天器集群控制方法

Spacecraft Cluster Control Method Based on Virtual Potential Field with Elliptic Cavity

摘要:

航天器集群由多个航天器在空间轨道上近距离飞行,进行信息交换,并相互协同共同完成空间任务。航天器集群作为智能集群在空间领域的表现形式,是智能集群的重要组成部分。当前,许多空间科学研究机构提出了多个航天器集群的研究计划,如 ANTS计划、APIES计划等。文章以在小行星带探测航天器集群为研究对象,提出了航天器集群的自组织控制方法,利用虚拟势场力使得与这个参考航天器构成最大距离可控的空间构型,从而保 证了航天器集群中的所有航天器共同构成松散空间构型。

Abstract:

Spacecraft cluster is comprised of many spacecraft, flying in near orbits, exchanging information, cooperatingwith each other to perform a space task. As a form of intelligent swarm in space science, spacecraft is an important part ofintelligent swarm. Up to now, space science research institutions have proposed multiple spacecraft cluster programs, suchas ANTs, APIES. In this paper, taking the spacecraft cluster for exploring asteroid belt as the research background, a self-organizing method for spacecraft cluster control was put forward, which was based on a virtual potential field with ellipticcavity and the spacecraft cluster was made to form a maximum distance controllable spatial configuration, thereby ensuringall the spacecraft keeping in a loose spatial cluster configuration.
