Abrupt and incipient fault isolation of nonlinear uncertain systems
(2000)This paper presents a robust fault diagnosis scheme for abrupt and incipient faults in nonlinear uncertain dynamical systems. A detection and approximation estimator is used for online health monitoring. Once a fault is ...

Bounds on the number of markings consistent with label observations in petri nets
(2009)In this paper, we consider state estimation in discrete-event systems (DESs) modeled by labeled Petri nets and present upper bounds on the number of system states (or markings) that are consistent with an observed sequence ...

The d-identifying codes problem for vertex identification in graphs: Probabilistic analysis and an approximation algorithm
(2006)Given a graph G(V, E), the identifying codes problem is to find the smallest set of vertices D ⊆ V such that no two vertices in V are adjacent to the same set of vertices in D. The identifying codes problem has been applied ...

Design and Stability Analysis of a Fault Accommodation Scheme for a Class of Nonlinear Dynamical Systems
(2000)The paper presents a robust fault diagnosis scheme for detecting and accommodating faults occurring in a class of nonlinear multi-input multi-output dynamical systems. Changes in the system dynamics due to a fault are ...

Distributed Fault Diagnosis in Discrete Event Systems via Set Intersection Refinements
(2018)We extend and verify diagnosability for a class of set intersection refinement strategies, which can be used for distributed state estimation and fault diagnosis in nondeterministic finite automata that are observed at ...

Fault diagnosis in discrete event systems modeled by partially observed petri nets
(2009)In this paper, we study fault diagnosis in discrete event systems modeled by partially observed Petri nets, i.e., Petri nets equipped with sensors that allow observation of the number of tokens in some of the places and/or ...

Fault diagnosis in discrete event systems modeled by petri nets with outputs
(2008)In this paper, we study fault diagnosis in discrete event systems modeled by Petri nets with outputs, i.e., Petri nets with place sensors and transition sensors. Faults are modeled as unobservable transitions and are divided ...

Max-product algorithms for the generalized multiple-fault diagnosis problem
(2007)In this paper, we study the application of the max-product algorithm (MPA) to the generalized multiple-fault diagnosis (GMFD) problem, which consists of components (to be diagnosed) and alarms/connections that can be ...

On the history of diagnosability and opacity in discrete event systems
(2018)This paper presents historical remarks on key projects and papers that led to the development of a theory of event diagnosis for discrete event systems modeled by finite-state automata or Petri nets in the 1990s. The goal ...

Performance analysis of sum-product algorithms for multiple fault diagnosis applications
(2010)In this paper, we study the application of sum-product algorithms (SPAs) to multiple fault diagnosis (MFD) problems in order to diagnose the most likely state of each component given the status of alarms. SPAs are heuristic ...

Reachability analysis for a class of petri nets
(2009)In this paper, we study the reachability problem for the class of (strictly) monotone Petri nets that we define based on algebraic conditions. More specifically, given a (strictly) monotone Petri net, an initial marking ...
