A fault-tolerant estimator is obtained from fusing the concept of fault detection with estimation. Two possible architectures are evaluated. At the center of the fault-tolerant estimation procedure is a bank of filters computing local state estimates, a residual screening scheme to isolate corrupted estimates and a method of blending untainted ones ...

On estimation of fault efficiency for path delay faults
Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat No 03CH37417) ATS-03, 2003In this paper, we propose a method to estimate fault efficiency for path delay faults based on untestable path analysis. In path delay fault testing, fault coverage of test patterns is usually, very low, because logic circuits often have huge number of paths including many untestable paths.

Estimating Fault Detection Effectiveness
2014 IEEE Seventh International Conference on Software Testing, Verification and Validation Workshops, 2014A t-way covering array can detect t-way faults, however they generally include other combinations beyond t-way as well. For example, a particular test set of all 5-way combinations is shown capable of detecting all seeded faults in a test program, despite the fact that it contains up to 9-way faults.

Abstract In this paper, whenever a single fault occurs at a time, we present conditions under which we can construct residual generators that enable us (1) to detect the fault either exactly or almostly (in either H2 or H∞ norm sense), and (2) to estimate the extent of fault (i.e. the fault signal) as best as possible, i.e. the estimation error is as

Estimators for Fault Tolerance Coverage Evaluation
IEEE Transactions on Computers, 1995Summary: This paper addresses the problem of estimating the \textit{coverage} of a fault tolerance mechanism through statistical processing of observations collected in \textit{fault injection} experiments. A formal definition of coverage is given in terms of the fault and system activity sets that characterize the input space.

Statistical estimation of delay fault detectabilities and fault grading
Journal of Electronic Testing, 1996In this paper, we present a statistical delay fault estimation technique. The basic method is an extension of STAFAN to include delay faults. A strategy to calculate the transition observabilities of fanout stems is proposed. Correlation within each fanout free region is considered in calculating gate line transition controllabilities.

Convergent Fault Estimation for Linear Systems With Faults and Disturbances
IEEE Transactions on Automatic Control, 2018The problem of convergent fault estimation for a class of linear systems with faults and disturbances is addressed for the first time in this technical note. A differential-equation-based convergence theorem of mean sequence of estimates is proposed, which provides an iterative mean estimation technique that has not been fully reported yet in the ...
