以无人机容错飞控系统的关键部件——容错飞控计算机为研究对象,提出了一种容错飞控计算机的硬件冗余和软件管理的余度管理设计方法。系统地介绍了容错飞控计算机的硬件体系结构和软件总体架构,并对其关键技术进行了分析。在无人发生故障时,容错飞控计算机能够快速、准确地检测、隔离故障,采取重构策略,确保无人机系统能够继续执行任务或安全返航。
Taking the fault-tolerant flight control computer, the key component of the UAV flight-fault-tolerant flight control system, as the research object, a margin-management design method for fault-tolerant flight-control computer hardware redundancy and software management was proposed. This paper systematically introduces the hardware architecture and software architecture of fault-tolerant flight control computer, and analyzes its key technologies. Fault-tolerant flight control computers detect and isolate faults quickly and accurately, and reconfigure strategies to ensure that the UAS can continue its mission or return safely in the absence of a human failure.
