摘　　要：针对全电推进卫星在小推力条件下姿态与轨道联合自主控制存在的难题,对3项关键技术——高承载比结构优化设计、高集成度电子系统架构优化设计和全电推进姿态与轨道联合自主控制开展研究。建立飞行事件的纵向与横向系统级架构,并采取多源信息融合及新场景下卫星功能软件定义,实现全电推进卫星平台的自主性;另外,提出连续小推力矢量最优指向的快速收敛,以及执行机构运动路径快速解算的星上算法,实现电推进点火过程的星上姿态与轨道策略实时快速生成。上述研究成果成功应用在东方红三号增强(DFH-3E)卫星平台首颗卫星亚太6E的工程实践中,可为我国后续全电推进卫星发展奠定技术基础。In order to solve the technical problem of the joint autonomous control of attitude and orbit under the small thrust,the research is conducted on three key technologies such as high load-bearing ratio structural optimization design,high integration electronic system architecture optimization design,and all-electric propulsion attitude and orbit joint autonomous control.The system-level architecture of flight events with vertical and horizontal perspective is established,and the multi-source information fusion and software-defined function under new scenarios are adopted,which helps to realize the autonomy of the all-electric propulsion satellite platform.On the other hand,the on-board algorithms for the rapid convergence of optimal thrust vectors and the fast solution of actuator motion paths are put forward,which realizes the on-board real-time fast generation of attitude and orbit strategies during the ignition.The above research results have been successfully applied in the engineering practice of APSTAR-6E satellite,the first satellite for DFH-3E satellite platform,which builds a technical foundation for the following development of all-electric propulsion satellites in China.
