Model extraction for fault isolation

2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583), 2005
This paper presents a simulation-based approach for fault isolation in complex dynamic systems. A machine learning technique is used to extract, from simulated data, models representing regularities in system behavior. A heuristic based on the degree of coverage of the model on the data is then applied to isolate faults. To test tolerance to incomplete

Overview of Fault Isolation

2023
Abstract This chapter briefly lays out the challenges associated with electrical fault isolation (EFI) brought on by continued transistor scaling and increasing package complexity. It also identifies high-priority issues and areas of technology that must be addressed for EFI tools and techniques to remain effective.

Fault Detection and Isolation in Systems with Parametric Faults

IFAC Proceedings Volumes, 1999
Abstract The problem of fault detection and isolation of parametric faults is considered in this paper. A fault detection problem based on parametric faults are associated with internal parameter variations in the dynamical system. A fault detection and isolation method for parametric faults is formulated in a standard setup and a synthesis method ...

Fault detection and fault isolation in the ground station

MILCOM 97 MILCOM 97 Proceedings, 2002
The satellite ground station environment is one in which the availability of the equipment is normally paramount. Satellite contacts may be scheduled at any time and the data being down-linked may be irreplaceable if the equipment in the ground station is not available to receive it.

Fault Detection and Isolation for Robotic Manipulators

Proceedings of the 2005 IEEE International Symposium on, Mediterrean Conference on Control and Automation Intelligent Control, 2005., 2005
This paper deals with the problem of detecting and isolating sensor faults in industrial robot manipulators. To the purpose, an analytical redundancy approach has been pursued, based on a bank of state observers for residual generation. An extended Hinfin approach is adopted to build the bank of residual generators; the compensation of poorly known ...

Fault isolation in an integrated diagnostic environment

IEEE Design & Test of Computers, 1993
The use of information flow models to conduct efficient fault isolation strategies is described. Of particular concern is optimizing diagnosis to minimize some objective cost function. A technique that can include multiple cost criteria such as test time, skill level, and failure frequency, as well as information value, is discussed. >

Fault detection and isolation: A graph approach

1999 European Control Conference (ECC), 1999
This paper is concerned with Fault Detection and Isolation (FDI). We consider structured linear systems for which the entries of the matrices are either fixed zeros or free parameters. To such systems, one can associate a directed graph and study generic properties.

Fault Tolerant Control and Fault Detection and Isolation

2011
This chapter formally provides a definition of the terms fault and failure and briefly discusses the different types of faults and failures which can occur in actuators and sensors—with specific aircraft examples. The chapter introduces the concept of fault tolerant control and gives a general overview of the different FTC and FDI research fields.

Incremental Fault Isolation for Dynamic Processes

2007
In this paper wc present an extension to the HS tree method for fault isolation developed by Reiter. This tool is combined with an ITMS based on root antecedents and used to perform incremental state based diagnosis on dynamic process systems. The approach is demonstrated to work by application to an industrial process — an ammonia washer system.

Fault Isolation Schemes

2013
In practice, fault isolation is, in most cases, the next step to be followed after a fault is detected. One of the widely used fault isolation strategies is to generate a bank of residual signals in such a way that each of them will only be influenced by a single fault. In Chap.
