基于群体智能的微纳卫星集群自主控制系统研究

Research on Micro-nano Satellite Swarm Autonomous Control System Based on Swarm Intelligence

随着卫星应用需求的发展,越来越多的航天任务已经不能仅靠单颗卫星来完成,而必须依靠多颗微纳卫星集群联合工作才能完成。文章针对星群面临的在轨运行管理和效能问题,研究了基于群体智能的微纳卫星集群自主控制系统,包括星群自主认知与自主决策技术、构型建立维持与重构技术和星间高低速协同通信技术等3个方面,对星群集群控制典型应用场景进行了仿真验证,结果表明:集群自主控制能够满足星群任务的实时性、轨道构型误差和星间动态网络等指标要求,可为推动微纳卫星集群在轨应用提供技术支撑。

With the development of satellite application requirements,more and more space missions can no longer be completed by a single satellite,but can be completed by the micro-nano satellite swarm.Aiming at the on-orbit operation management and efficiency problems,this paper studies micro-nano satellite swarm autonomous control based on swarm intelligence,including three aspects:satellite swarm autonomous recognition and decision,configuration establishment maintenance and reconstruction,and inter-satellite high and low rate cooperative communication technology.Finally,satellite swarm control has been preliminarily simulated and verified for typical application scenes,and the results showed that satellite swarm autonomous control can meet the requirements of real-time performance,orbital configuration error,an inter-satellite dynamic network,providing support for the on-orbit application of micro-nano satellite swarm.
