模糊离散事件系统的多故障诊断
Multiple Failures Diagnosability of Fuzzy Discrete Event Systems
摘要
Abstract
In the classical failure diagnosis of discrete event systems,the diagnoser can not rely on itself judgment whether it can be diagnosed,we need to refer to the original system.Aimed at this drawback,in this paper,the multiple failures diagnosability is proposed based on the concept of undistinguishable strings in the fuzzy discrete event systems.Firstly,we construct the diagnoser with respect to the minimal observable event corresponding to fuzzy automaton to find sets of undistinguishable strings.Secondly,according to the properties of the diagnose,a necessary and sufficient condition for multiple failures diagnosability of fuzzy discrete event systems is put forward.Finally,the experimental results show that the proposed method is an effective and simple approach for multiple failures diagnosability of fuzzy discrete event systems.关键词
