中文摘要
      自主诊断重构是确保航天器控制系统安全可靠自主运行的关键技术之一。本文针对航天器资源严重受限的客观情况,改变传统一味追求华丽算法与豪华配置的设计理念,从航天器的自身特性出发,深入挖掘诊断重构问题的本质,提出基于可诊断性与可重构性评价设计的研究思路。文章首先介绍了航天器自主诊断重构技术的发展现状,分析了当前技术的不足之处并探究了其深层原因;然后,提出了通过可诊断性与可重构性评价设计从根本上提高系统自主诊断重构能力的全新思路,梳理了其研究内容与研究概况;最后,对航天器控制系统自主诊断重构技术的发展趋势进行了展望。
英文摘要
      Autonomous fault diagnosis and reconfiguration is an important and effective way to ensure the safe and reliable operation of spacecraft. Considering the objective situation that the resources available for spacecraft are severely limited, this paper changes the traditional design concept of blindly pursuing fancy algorithm and luxury fittings. A new design concept based on the system diagnosability and reconfigurability evaluation and design is proposed here, deeply exploring the nature of diagnosis and reconfiguration technology by investigating the system characteristics of spacecraft. Firstly, the development status of autonomous diagnosis and reconfiguration technology of spacecraft is introduced, and the shortcomings of the current technology are analyzed with their causes deeply explored. Then, a new idea to improve the system capacity of autonomous diagnosis and reconfiguration through the system diagnosability and reconfigurability evaluation and design is put forward. Finally, the development trend of autonomous diagnosis and reconfiguration technology of spacecraft control system is prospected.
