分布式随机离散事件系统的模式故障安全诊断
Safe Diagnosis of Pattern Failure of Decentralized Stochastic Discrete Event Systems
摘要
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.关键词
