Fault Detection and Isolation

2001
Fault detection and isolation are important elements of fault tolerant control systems as discussed in Chapter 8. This chapter outlines the current state of the art of fault detection and isolation (FDI) for the purpose of designing fault-tolerant control systems. Signal-based as well as quantitative and qualitative model-based approaches are explained,

Statistical Demonstration of Fault-Isolation Requirements

IEEE Transactions on Reliability, 1980
Methods are developed for obtaining the best test for the attribute demonstration testing of fault isolation requirements. Because fault isolation requirements are generally stated in terms of the probabilities of several events the multinomial distribution is used. Tables of required sample sizes are given for numerous commonly used cases.

Dynamic fault dictionaries and two-stage fault isolation

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 1998
This paper presents dynamic two stage fault isolation for sequential random logic VLSI circuits, and introduces limited and dynamic fault dictionaries. In the first stage of the dynamic process, a limited fault dictionary identifies candidate faults, which are further distinguished in the second stage by a dictionary generated dynamically for the ...

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.

Fault isolation for multimode process

2016 Chinese Control and Decision Conference (CCDC), 2016
In this paper, the fault reconstruction algorithm based on between-mode dependency analysis is presented to realize fault diagnosis. Firstly, the independent components which are extracted by kernel independent component analysis (KICA) are used to find the relationship between different modes.

Fault isolation with insufficient measurements

IEEE Transactions on Circuit Theory, 1973
A technique is given for approximating the "most likely" values of the internal components of a system when insufficient measurements have made their exact determination impossible. It is limited to linear systems, all of whose measurements are made at a single frequency and whose connections can be represented by sets of linear algebraic equations ...

Fault isolation for nonisolated blocks

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2004
We consider circuits represented as interconnections of logic blocks. In such circuits, the goal of fault isolation is to identify which one of the blocks is faulty based on a faulty output response produced by the circuit. We study this issue and demonstrate that perfect or close-to-perfect fault isolation is possible with tests that propagate fault ...

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.

Roadmaps: Advanced Fault Isolation Techniques

EDFA Technical Articles, 1999
Abstract Technologies relatively new to failure analysis, like time-correlated photon counting, electro-optical probing, antireflective (AR) coating, Schlieren microscopy, and superconducting quantum interference (SQUID) devices are being leveraged to create faster, more powerful tools to meet increasingly difficult challenges in failure
