Design of a state observer using decay rate LMI constraints for fault detection in mechanical systems
(2010-01-01)
Nowadays, one of the most important concerns for many companies is to maintain the operation of their systems without sudden equipment break down. Because of this, new techniques for fault detection and location in mechanical ...

Characterizing a Detection Strategy for Transient Faults in HPC
(Editorial de la Universidad Nacional de La Plata (EDULP), 2016)
Sliding mode for detection and accommodation of computation time delay fault
(Elsevier B.V., 2009-10-01)
Computation time delay in digital control systems reduces its robustness as well as degrades its performance. In this paper, the computation time delay is assumed to be constant and smaller than the sampling time and is ...
Hybrid fault diagnosis scheme implementation for power distribution systems automation
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Power distribution automation and control are import-ant tools in the current restructured electricity markets. Unfortunately, due to its stochastic nature, distribution systems faults are hardly avoidable. This paper ...
Fault detection and isolation using concatenated wavelet transform variances and discriminant analysis
(2006)
A method for fault detection and isolation is developed using the concatenated variances of the continuous wavelet transform (CWT) of plant outputs. These concatenated variances are projected onto the principal component ...
Fault Detection in Power Distribution Systems Using Automated Integration of Computational Intelligence Tools
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
The main purpose of this paper is to present architecture of automated system that allows monitoring and tracking in real time (online) the possible occurrence of faults and electromagnetic transients observed in primary ...
Single-observer based current sensor fault tolerant control for IM traction drives
(Institute of Electrical and Electronics Engineers, 2021-12)
In this work, a current sensors fault tolerant control system (FTCS) for induction motor traction drives is proposed. The FTCS uses a single observer for the detection and isolation of disconnection and gain faults occurred ...
Detection and isolation of faults on the rotor side converter of doubly fed induction generatorsDiagnóstico de fallas en el convertidor del rotor en generadores de inducción con rotor bobinado
(Comite Espanol Automatica Cea, 2018-01)
This article presents a fault diagnosis strategy for open switch faults in the rotor side converter of doubly fed induction generators. The proposed strategy uses state observers based on dynamic models obtained from an ...
