Faults accommodation based on online fault identification

2009 Chinese Control and Decision Conference, 2009
In this paper, we consider the fault accommodation for a class of linear time invariant (LTI) systems with an innovation form. The considered faults are mainly sensor and actuator faults. In the first place, the underlying faults are parameterized such that they can be estimated using the input-output data. If the system is time invariant, the actuator

Fault Identification by Passive Testing

2004
In this paper, fault identification in passive testing is investigated. First, the fault detection algorithm and an existing fault identification algorithm in passive testing are introduced. Then, two more efficient fault identification algorithms which can give out fewer possible faults than the existing one are proposed.

Identification of feedback bridging faults with oscillation

Proceedings Eighth Asian Test Symposium (ATS'99), 2003
When a feedback bridging fault occurs in a combinational circuit and it is activated, logical oscillation may be generated in the circuit. In this paper, the necessary conditions are presented for feedback bridging faults to generate logical oscillation. Also, a method is proposed to identify such faults in feedback bridging ones.

Identification of undetectable faults in combinational circuits

Proceedings 1989 IEEE International Conference on Computer Design: VLSI in Computers and Processors, 2003
Identification of undetectable faults is essential for preventing test invalidation due to the occurrence of such faults, and for improving the efficiency of test generation. Methods for identifying undetectable faults in combinational circuits by analyzing regions between fanout stems and reconvergent gates are presented.

Scalable robot fault detection and identification

Robotics and Autonomous Systems, 2006
Abstract Experience has shown that even carefully designed and tested robots may encounter anomalous situations. It is therefore important for robots to monitor their state so that anomalous situations may be detected in a timely manner. Robot fault diagnosis typically requires tracking a very large number of possible faults in complex non-linear ...

Fault identification in robust data structures

[1989] The Nineteenth International Symposium on Fault-Tolerant Computing. Digest of Papers, 2003
An optimal algorithm is presented for the identification of faulty attributes in a robust data structure. The algorithm does not use any fault syndrome table since the size of such a table could be large, particularly when faults can compensate one another arbitrarily.

Identification of faults using sparse optimization

2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2014
This paper describes a fault identification method based on the equivalence between the fault current drawn at an arbitrary point along a given line section and a pair of virtual superimposed current injections at the terminal nodes of the same line section.

Identification and test generation for primitive faults

Proceedings International Test Conference 1996. Test and Design Validity, 2002
We propose a new method to identify and test primitive faults in combinational circuits described as multi-level or two-level netlists. A primitive fault is a multiple path delay fault for which none of the single paths contained in the fault is robustly or non-robustly testable while the presence of the fault can degrade the circuit performance ...

Fault Reconstruction and Identification

2012
This chapter introduces fault reconstruction and identification methods, particularly for those processes whose data follow non-Gaussian distributions. For non-Gaussian fault detection, recent work has demonstrated the effectiveness of Independent Component Analysis (ICA) to extract non-Gaussian source signal and Support Vector Data Description (SVDD ...

On minimizing testing rounds for fault identification

[1988] The Eighteenth International Symposium on Fault-Tolerant Computing. Digest of Papers, 2003
A bound is obtained for the number of rounds of testing sufficient to identify the faulty units of a system. Within a single round each unit may participate in at most one test. The authors give an adaptive algorithm which works in O(log/sub (n/t)//sup t/) rounds and uses O(n) tests.
