本笔记研究部分可观测离散事件系统中的分布式故障诊断问题，该系统由一组智能体进行监控，以在有限步数内协同诊断故障。本研究的创新之处在于提出了一种方法，用于验证即使存在传输延迟损害时故障是否仍可被诊断。为解决该场景，本文提出了一种新的分布式可诊断性条件，该条件扩展了文献中提出的分布式可诊断性条件。随后通过一种名为延迟记录器的新型结构和新的诊断函数来验证该分布式可诊断性条件。理论分析表明，该验证方法可成功确定故障是否能够被诊断。
英文摘要
This note studies the distributed fault diagnosis problem in partially-observed discrete event systems, where the system is monitored by a group of agents to cooperatively diagnose faults within a finite number of steps. The novelty of this work is the creation of a methodology to verify when the faults can be diagnosed even in the presence of transmission delay impairments. To address this scenario, a new distributed diagnosability condition is proposed, which extends decentralized diagnosability conditions proposed in the literature. Such distributed diagnosability condition is then verified via a novel structure named delay recorder and a new diagnosis function. Theoretical analysis shows that the verification method can successfully determine whether the faults can be diagnosed.
