Substation fault identification
2010 IEEE International Conference on Industrial Technology, 2010This paper introduces a new procedure in order to localize and identify a given resistive fault during power system operation. A simple linear identification approach is presented for the ideal noiseless case. For the real noisy situation an algorithm is shown to extract the desired information, allowing to easily identifying buses connected to the ...

Primitive Path Delay Fault Identification
Proceedings Tenth International Conference on VLSI Design, 1998We present a novel and efficient method to identify all primitive single and multi path delay faults (PDFs) in multi-level combinational circuits. Our method is the first one to successfully target the primitive PDF identification problem for multi-level circuits-previous research results in this area have been limited either to the identification of ...

PARAMETRIC IDENTIFICATION FOR ROBUST FAULT DETECTION
IFAC Proceedings Volumes, 2002Abstract The work presents some simulation results concerning the application of robust model–based fault diagnosis to an industrial process by using identification and disturbance de–coupling techniques. The first step of the considered approach identifies several equation error models by means of the input–output data acquired from the monitored ...

Faults accommodation based on online fault identification
2009 Chinese Control and Decision Conference, 2009In 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 and accommodation for incipient and abrupt faults
2007 46th IEEE Conference on Decision and Control, 2007This paper proposes a fault tolerant control strategy for failures belonging to a class of functions including both incipient and abrupt faults. To this purpose a sliding mode controller has been designed ensuring the robust boundedness of system trajectories.

From Fault-Tree To Fault-Identification
IEEE Transactions on Reliability, 1983Summary: A practical way is given of identifying actual faults, by using a fault tree's complete system of minimal cutsets. For instance, for a fault tree where 20 cutsets are considered with 30 possible primal events, any of them can be found in at most three steps by the proposed FID-algorithm.

On Fault Identification in Diagnosable Systems
IEEE Transactions on Computers, 1981This paper begins by giving a characterization of t1/ t1—diagnosable systems. Then a class of t0-diagnosable systems, denoted by d(n,t0,X), is considered. It is shown for any member of this class that: 1) necessary and sufficient conditions for t1/t1—diagnosability are greatly simplified, 2) optimal diagnosis algorithms of time complexity 0(nt0) exist,

Fault Identification Techniques
2013Fault identification can be considered as an important objective of a fault diagnosis framework. The identification result helps fault isolation through comparing the estimated parameter values with their nominal ones. In addition, the estimated size of faults can provide useful information to achieve fault tolerant control.
