| 摘 要： | 以模糊自动机为模型，研究模糊离散事件系统基于模式的故障诊断问题.先针对S类型和T类型两种故障模式，分别对模糊离散事件系统的S类型模式可诊断性和T类型模式可诊断性进行了形式化，再通过构造S类型模式诊断器和T类型模式诊断器，分别得到了模糊离散事件系统关于S类型模式可诊断性和T类型模式可诊断性的充分必要条件，实现了模糊离散事件系统基于模式的故障诊断.

| Abstract: | Failure diagnosis of discrete event systems (DESs) has received considerable attention in recent years. The failure diagnosis for fuzzy discrete event systems (FDESs) modeled by fuzzy automata is investigated. First, for two kinds of failure patterns:S type pattern and T type pattern, the notions of diagnosability for S type pattern and for T type pattern of FDESs are respectively formalized. Then by constructing S type pattern diagnoser and T type pattern diagnoser, the necessary and sufficient conditions for the diagnosability of S type pattern and T type pattern of FDESs are respectively proposed, and the pattern-based failure diagnosis of FDESs is realized. |
