面向多航天器协同的自主任务规划方法研究

Research on Self-organization Mission Planning for Multi-spacecraft Coordination

针对多航天器的协同任务规划,设计了一种基于多Agent技术的体系结构,将航天器任务体系分为多航天器协同层、系统层和分系统层的多层结构,分析了同构式多航天器以及异构式多航天器的任务差异,给出了多航天器协同任务模型;在此基础上,提出了多航天器的招投标任务协商策略和评估发布协商策略,以及基于SGPLAN的任务协同算法;以多航天器进行推进补加问题为例通过仿真进行了验证,表明了模型的合理性以及算法的有效性,为多航天器协同任务实际应用提供了一种可行的方法。

A novel spacecraft autonomy architecture based on Multi-agent is put forward to fulfill the self-organization mission planning demands of multi-spacecraft-coordination.The architecture is divded into Multi-spacecraft-coordination Layer,Spacecraft System Layer and Spacecraft subsystem Layer.The difference between isomorphic spacecraft and heterogeneous spacecraft is analysed,and the model of multi-spacecraft coordination has been taken.On this basis,bidding mechanism and estimate-publishment mechanisim is designed for the two kind of multi-spacecraft mission planning,and the algorithm based of SG Plan.has been taken.At last,multi-spacecraft propellant refueling problem was taken as an example,and satisfactory results were obtained through simulation,which shows that the model was reasonable and the algorithm was efficient.The self-organization mission planning in this article can be refered to real multi-spacecraft-coordination application.
