摘要： 本文研究分布式模糊离散事件系统的模式故障安全诊断问题，提出一种基于模式故障安全协同诊断器的模式故障安全诊断方法。先在模糊离散事件系统中引入模式故障和模式故障安全诊断概念。然后对模糊离散事件系统的模式故障安全协同可诊断性进行了形式化定义。为了进一步验证分布式模糊系统的模式故障安全诊断性，构建了一个模式故障安全协同诊断器，并提出了一个关于分布式模糊离散事件系统的模式故障安全诊断的充分必要条件，实现了分布式模糊离散事件系统的模式故障安全诊断。

Abstract: This paper investigates the problem of pattern failure safe diagnosis of decentralized fuzzy discrete event systems, and proposes a pattern failure safe diagnosis method based on pattern failure safe codiagnoser. Specifically, we first introduce the concepts of pattern failure and safe diagnosis of pattern failure in fuzzy discrete event systems, and then formalize the notion of safe codiagnosibility of pattern failure for fuzzy discrete event systems. Moreover, to verify the pattern failure safe codiagnosibility of decentralized fuzzy systems, we construct the pattern failure safe codiagnoser is constructed, and developa necessary and sufficient condition for the safe codiagnosibility of pattern failure. By doing these, the pattern failure safe diagnosis of decentralized fuzzy discrete event systems can be performed based on the pattern failure safe codiagnoser.

Key words: fuzzy discrete event systems, safe diagnosis, pattern failure, codiagnoser
