卫星姿态控制系统容错控制综述

Fault-tolerant control of satellite attitude control systems: Review

主要针对卫星姿态系统容错控制研究领域已有的成果进行了回顾。总结了国内外卫星容错控制的现有成果,主要从卫星姿态控制系统的可重构性、单体卫星容错控制和卫星编队容错控制3个部分对相关的研究成果进行了归纳分析。其中,卫星姿态系统的可重构性从重构目标和系统功能要求两方面进行分析;对单体卫星容错控制现状的介绍主要从自适应技术、滑模理论、预设性能、干扰观测器、故障估计观测器几个方面展开;卫星编队容错控制方法从独立容错、协同容错、拓扑重构和组成重构的角度进行阐述。最后进行总结,并展望了卫星姿态控制系统容错控制领域未来可能出现的新问题和研究思路。

The achievements in the research field of fault-tolerant control of satellite attitude systems are reviewed. The results of satellite attitude fault-tolerant control at home and abroad are summarized and analyzed from three parts: the reconfigurability of satellite attitude systems, single satellite fault-tolerant control, and satellite formation fault-tolerant control. The reconfigurability of the satellite attitude system is analyzed from two aspects: reconstruction goals and system functional requirements. The introduction of the current status of single satellite fault-tolerant control mainly includes the adaptive technology, sliding mode theory, prescribed performance, disturbance observer and fault estimation observer. The satellite formation fault-tolerant control methods are explained from the perspectives of independent fault tolerance, cooperative fault tolerance, topology reconstruction, and composition reconstruction. Finally, a summary of this article is provided, and new problems and research ideas in fault-tolerant control of satellite attitude control systems are prospected.
