Diagnosis of Intermittent Faults [PDF]
Discrete Event Dynamic Systems, 2004 Discrete event systems (DESs) are considered for which faulty behaviour occurs ``intermittently'', with fault events \(f_i\), \(i=1,\dots,m\), followed by reset events \(r_i\), \(i=1,\dots,m\), followed by new occurrences of fault events, and so forth.

Incremental fault diagnosis [PDF]
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2005 Fault diagnosis is important in improving the circuit-design process and the manufacturing yield. Diagnosis of today's complex defects is a challenging problem due to the explosion of the underlying solution space with the increasing number of fault locations and fault models. To tackle this complexity, an incremental diagnosis method is proposed. This

Foundations and Trends® in Systems and Control, 2016 This tutorial investigates the problem of the occurrence of multiple faults in the sensors used to monitor and control a network of cyberphysical systems. The goal is to formulate a general methodology, which will be used for designing sensor fault diagnosis schemes with emphasis on the isolation of multiple sensor faults, and for analyzing the ...
