Comparative study of inversion-based and observer-based approaches for fault diagnosis in DC-DC converters
Recently, model-based approaches have been proposed for fault diagnosis as an emerging alternative to traditional techniques. Particularly, the inversion-and observer-based were proposed for fault diagnosis as successful ...
An Industrial Internet Application for Real-Time Fault Diagnosis in Industrial Motors
Being able to detect, identify, and diagnose a fault is a key feature of industrial supervision systems, which enables advance asset management, in particular, predictive maintenance, which greatly increases efficiency and ...
Time-frequency analysis combining wavelets and the envelope technique for fault identification in rotary machines
Nowadays the method based on demodulation by envelope finds wide application in industry as a technique for evaluation of bearings and other components in rotating machinery. In recent years the application of Wavelets for ...
An Illustration of some methods to detect faults in geared systems using a simple model of two meshed gears
Gears are the components in many mechanical systems that are likely to develop faults due to their dynamic characteristics, such as the cyclic loading applied to the meshing teeth. The main faults in gears are pitting and ...
Wavelet-based analysis and detection of traveling waves due to DC faults in LCC HVDC systems
A Probabilistic Fault Detection Approach: Application to Bearing Fault Detection
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011-05)
This paper introduces a method to detect a fault associated with critical components/subsystems of an engineered system. It is required, in this case, to detect the fault condition as early as possible, with specified ...
A model based fault detection and diagnosis system for rolling mill equipments
In this paper, the implementation of a Model Based Fault Detection and Diagnosis System, that uses fuzzy logic to determinate the nature of the detected faults in rolling mill equipments is presented. The system is built ...
A fault detection and isolation system for cooperative manipulators
(Sociedade Brasileira de Automática, 2008)
The problem of fault detection and isolation (FDI) in cooperative manipulators is addressed in this paper. Four FDI procedures are developed to deal with free-swinging joint faults, locked joint faults, incorrectly measured ...
