New Results on Decentralized Diagnosis of Discrete Event Systems
The past decade has witnessed the development of a body of theory, with associated applications, for fault diagnosis of dynamic systems that can be modeled in a discrete event systems framework. This paper presents several new notions of diagnosability, together with on-line diagnosis decision rules, in the context of a general decentralized architecture that allows for the use of “conditional ...
متن کاملFault diagnosis in discrete-event systems: framework and model reduction
A state-based approach for on-line passive fault diagnosis in systems modelled as finite-state automata is presented. In this framework, the system and the diagnoser (the fault detection system) do not have to be initialized at the same time. Fhrthermore, no information about the state or even the condition (failure status) of the system before the initiation of diagnosis is required. The desig...
متن کاملMulti-resolution Fault Diagnosis in Discrete-event Systems
Multi-Resolution Fault Diagnosis in Discrete-Event Systems . JiangJing Pan Concordia University In this thesis, a framework for multi-resolution fault diagnosis in discrete-event systems (DES) is introduced. Here a sequence of plant models, with increasing resolution, are used in fault diagnosis and the range of possible diagnosis is narrowed down step by step, until the failure mode is isolate...
متن کاملRecent Developments in Discrete Event Systems
This article is a brief exposure of the process approach to a newly emerging area called "discrete event systems" in control theory and summarizes some of the recent developments in this area. Discrete event systems is an area of research that is developing within the interstices of computer, control and communication sciences. The basic direction of research addresses issues in the analysis an...
متن کاملDecentralized approach for fault diagnosis of discrete event systems
This paper proposes a decentralized approach to realize the diagnosis of Discrete Event Systems (DES). This approach is based on a set of local diagnosers, each one of them diagnoses faults entailing the violation of the local desired behavior. These local diagnosers infer the fault’s occurrence using event sequences, time delays between correlated events and state conditions, characterized by ...
