Decentralized prognosis of fuzzy discrete-event systems
This paper gives a decentralized approach to the problem of failure prognosis in the framework of fuzzy discrete event systems (FDES). A notion of co-predictability is formalized for decentralized prognosis of FDESs, where several local agents with fuzzy observability rather than crisp observability are used in the prognosis task. An FDES is said to be co-predictable if each faulty event can be...
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 ...
متن کاملFault Diagnosis in Nonlinear Systems Using Interconnected Sliding Mode Observers
This paper presents a new technique for fault diagnosis and estimation of unknown inputs in a class of nonlinear systems. The novelty of the approach is governed by the use of two interconnected sliding mode observers. The first of the two observers is used for fault diagnosis and the second is used for the reconstruction of unknown inputs. The two observers exchange their respective reconstruc...
متن کاملRealization of interconnected nonlinear input-output discrete-time systems
The majority of control techniques for nonlinear systems are based on state-space description, the problem of finding state-space realization of input-output system is an important task. This paper is devoted to the problem of realizability of the interconnections of the nonlinear discretetime input-output systems. Necessary and sufficient conditions are given for the existence of a state-space...
متن کاملA Decentralized Stabilization Scheme for Large-scale Interconnected Systems
This thesis considers the problem of decentralized control of large-scale systems by means of a decomposition and decentralization approach. Having decomposed the system into a number of interconnected subsystems a set of local decentralized controllers is constructed for individual subsystems. An important issue is to adapt methods with existing information structure constraints. Namely, somet...
