摘要
现有分布式随机离散事件系统的研究都集中在单个事件导致的故障上,然而许多实际应用系统所发生的故障往往是由一系列事件相继发生而导致的.针对此类故障的检测问题,本文提出了一种随机离散事件系统的模式故障安全协同诊断方法.首先,对分布式随机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.然后,通过构造模式故障安全协同诊断器,提出了一个基于安全协同诊断器的分布式随机离散事件系统的模式故障安全协同可诊断性的充要条件,实现了分布式随机离散事件系统的模式故障安全诊断.
Abstract
Most existing studies of decentralized stochastic discrete-event systems(SDESs)usually focused on faults caused by a single event,while in many practical applications,faults were usually resulted from the successive occurrence of a series of events.To address the problem of detecting such faults,in this paper,a pattern safe diagnosis method is proposed for decentralized SDESs.First,the notion of pattern safe codiagnosability of decentralized stochastic systems is formalized.Then,by constructing a pattern safe codiagnoser,a sufficient and necessary condition of pattern safe codiagnosability is presented based on the pattern safe codiagnoser for decentralized SDESs.As a result,the pattern safe diagnosis for decentralized SDESs can be performed.
