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.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.
