摘要
面向我国深空探测任务对空间飞行器安全可靠自主运行提出的迫切需求,研究了空间飞行器自主诊断重构技术。针对空间飞行器诊断重构能力确定于设计之初、受制于有限资源等特点,提出了着力于系统评价设计过程的自主诊断重构方法。首先,分析了国内外研究现状并梳理了后续的待突破难点。其次,以可诊断性与可重构性理论为指导,提出了正常模式与故障模式一体化设计方法、故障诊断与系统重构一体化设计方法,在设计阶段通过资源配置和诊断重构方案的综合优化实现系统诊断重构能力最大化。然后,提出了基于能力在轨评估的诊断重构方案动态调整方法,在运行阶段通过诊断重构过程的自适应调整保持系统最优状态,进而从全寿命周期提升系统的诊断重构能力。最后,进行了总结与展望。
To meet the urgent demand of safe,reliable and autonomous operation of spacecraft in China’s deep space exploration missions,the autonomous diagnosis and reconfiguration technology for spacecraft is studied.Since the fault diagnosis and system reconfiguration capability of spacecraft is determined at the beginning of the designing and is limited by available resources,an autonomous fault diagnosis and system reconfiguration method focusing on the system evaluation and design is proposed.Firstly,the status of relevant research and the difficulties to be overcome in the future are analyzed.Then,aiming at these difficulties,guided by the theory of spacecraft diagnosability and reconfigurability,the integrated design method of normal and fault modes,as well as the integrated design method of fault diagnosis and system reconfiguration are proposed to maximize the system diagnosability and reconfigurability through the optimization of resource allocation and diagnosis/reconfiguration scheme at the designing stage.Moreover,the adjustment method of diagnosis and reconfiguration scheme based on capability on-orbit evaluation is proposed to maintain the optimal system state through adaptive adjustment of the diagnosis and reconfiguration process in the operation stage.Finally,the summary and prospects are given.
