Fault diagnosis scheme for open-circuit faults in field-oriented control induction motor drives
(The Institution of Engineering and Technology, 2013-05)
In this study, a new model-based fault detection and isolation (FDI) strategy is proposed for field-oriented control (FOC) induction motor (IM) drives. Actuator faults are addressed, and specifically, single open-circuit ...

(2013-03-18)
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 ...
System-Level Fault Diagnosis with Dynamic Mesh Optimization
(Revista Computación y Sistemas; Vol. 16 No. 2, 2012-06-05)
Abstract. The efficient identification of hardware and software faults in parallel and distributed systems still remains a challenge in today's most prolific decentralized environments. System-level fault diagnosis is ...
Rotor fault diagnosis in permanent magnet synchronous machine using the midpoint voltage of windings
(Institution of Engineering and Technology, 2020-02)
A new strategy is proposed here for the diagnosis of asymmetric demagnetisation in permanent magnet synchronous machines. The strategy is based on the measuring of the voltage at the midpoint of the windings within a phase. ...
Optimal sensor network upgrade for fault detection using principal component analysis
(American Chemical Society, 2016-02-11)
The efficiency of a fault monitoring system critically depends on the structure of the plant instrumentation system. For processes monitored using principal component analysis, the multivariate statistical technique most ...
