Kalman Filter Based Method for Fault Diagnosis of Analog Circuits

This paper presents a Kalman filter based method for diagnosing both parametric and catastrophic faults in analog circuits. Two major innovations are presented, i.e., the Kalman filter based technique, which can significantly improve the efficiency of diagnosing a fault through an iterative structure, and the Shannon entropy to mitigate the influence of component tolerance. Both these concepts ...

Multiple Fault Diagnosis of Analog Circuits Based on Large Change Sensitivity Analysis

A new method is proposed in this paper for multiple fault diagnosis in linear analog circuits. The test equation in the traditional large change sensitivity method is modified to establish the linear relationship between the measurements and the faulty parameter deviations with the coefficient matrix derived from the nominal values of circuit parameters. By using a recently developed method to ...

Fault Diagnosis of Analog Circuits Using Extension Genetic Algorithm

This paper proposed a new fault diagnosis method based on the extension genetic algorithm (EGA) for analog circuits. Analog circuits were difference at some node with the normal and failure conditions. However, the identification of the faulted location was not easily task due to the variability of circuit components. So this paper presented a novel EGA method for fault diagnosis of analog circ...

A Fault Diagnosis Algorithm of Analog Circuits Based on Node-voltage Relation

A new method of diagnosis of single faults of passive elements in analog electronic circuits, based on the node-voltage relation approach, is presented. This method consists of two parts: creation of a fault dictionary describing the nominal state of the tested circuit and containing indirect parameters representing respective faults, and a new fault detection and localization algorithm.
