Fault isolation in grey systems

International Test Conference 1988 Proceeding@m_New Frontiers in Testing, 2003
The concepts of grey, white, and black systems are formally introduced and developed into logic testing area, i.e. the area of error detection and fault isolation, to find a direction to establish more efficient test schemes for testing digital systems at a reasonable cost.

Large-scale fault isolation

IEEE Journal on Selected Areas in Communications, 2000
Of the many distributed applications designed for the Internet, the successful ones are those that have paid careful attention to scale and robustness. These applications share several design principles. In this paper, we illustrate the application of these principles to common network monitoring tasks.

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,

Portable Software Fault Isolation

2014 IEEE 27th Computer Security Foundations Symposium, 2014
We present a new technique for architecture portable software fault isolation (SFI), together with a prototype implementation in the Coq proof assistant. Unlike traditional SFI, which relies on analysis of assembly-level programs, we analyze and rewrite programs in a compiler intermediate language, the Cminor language of the Comp Cert C compiler.

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 ...

Isolability of faults in sensor fault diagnosis

Mechanical Systems and Signal Processing, 2011
Abstract A major concern with fault detection and isolation (FDI) methods is their robustness with respect to noise and modeling uncertainties. With this in mind, several approaches have been proposed to minimize the vulnerability of FDI methods to these uncertainties.

Fault isolability conditions for linear systems with additive faults

2006 American Control Conference, 2006
In this paper, we shall show that an unlimited number of additive single faults can be isolated under mild conditions if a general isolation scheme is applied. Multiple faults are also covered. The approach is algebraic and is based on a set representation of faults, where all faults within a set can occur simultaneously, whereas faults belonging to ...

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 Detection and Isolation of Actuator Faults in Overactuated Systems

2007 American Control Conference, 2007
This paper investigates development of fault detection and isolation (FDI) filters for overactuated systems. Due to input channels coupling effects and dependencies in overactuated systems, the necessary condition for applying geometric FDI approaches is not satisfied. In this work a geometric FDI approach for linear systems is extended to overactuated
