, 1988 A simulation-after-test algorithm for the analog fault diagnosis problem is presented, in which a bound on the maximum number of simultaneous faults is used to minimize the number of test points required. Based on this self-testing algorithm, an analog automatic test program generation (AATPG) for both linear and nonlinear circuits and systems is being

Publisher Summary This chapter focuses on fault diagnosis. The precise skills required for fault finding are hard to define; they are easily acquired by some while others find the lessons difficult to learn. Fault finding is a logical pursuit in which there is still plenty of room for flair and imagination. Fortunately, those who have already acquired

Time has been shown to be determinant in many diagnosis situations. A way to account for time is to enrich the fault signature matrix with time information. However this requires to anticipate the symptoms occurrence order or provide estimates for the symptom occurrence dates.

Fault monitoring and diagnosis
Computing & Control Engineering Journal, 1990A technique for both monitoring and diagnosing a range of subtle faults in an arbitrary dynamic system is presented. With minor modification, the technique can be extended to encompass sensor fault diagnosis and is well suited to accommodation within a real-time Al management system. It is based on signal processing of signals from conventional sensors

On the diagnosis of Byzantine faults
Proceedings [1988] Seventh Symposium on Reliable Distributed Systems, 2003The class of evidence-based diagnosis algorithms is developed to identify Byzantine (and any other faulty) processors. Such algorithms are said to be fair if they identify no failure-free processor as faulty. This paper makes two significant contributions: (i) it introduces a very general and simple formal model of the evidence-based diagnosis ...

The diagnosis of randomly occurring faults in complex electronic equipment is a difficult task which is generally not done well. The paper reviews some of the work on the content of the fault-diagnosis training course. In particular, the approach of the Technical Training Command of the Royal Air Force is discussed. Research has shown that the teaching

Fault diagnosis in photovoltaic arrays
2015 International Conference on Clean Electrical Power (ICCEP), 2015This paper proposes a simple automatic technique for fault diagnosis in photovoltaic (PV) arrays, based on the analysis of the an omalies observed in the I-V characteristic. Firstly, the I-V characteristic of the PV array is simulated using Matlab/Simscape tool for different faulty conditions; which is experimentally validated by generating different ...

Pumps are basic components in most technical processes, like in power and chemical industries, mineral and mining, manufacturing, heating, air conditioning and cooling of engines. They are mostly driven by electrical motors or by combustion engines and consume a high percentage of electrical energy.

The power of supervisory control and data acquisition (SCADA) systems employed in electrical power systems has continuously increased since their initial introduction. Together with the advances in computing power available at system control centres, the effect of this has been a significant increase in the volume of data presented to system operators.
