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 ...
Stator inter-turn faults diagnosis in induction motors using zero-sequence signal injection
(Institution of Engineering and Technology, 2020-12)
This study presents a strategy for stator inter-turn faults diagnosis in induction motors (IMs) operating under timevariable load and time-variable speed conditions. The strategy consists in injecting a zero-sequence ...
Detection and isolation of current-sensor and open-switch faults in electric traction drives
(Institute of Electrical and Electronics Engineers, 2021-08)
In this work, a strategy for detection and isolation of current-sensors and open-switch faults in electric traction drives is proposed. An induction motor drive with only two current sensors is considered for the design ...
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 ...
Open-Circuit Fault Identification Method for Interleaved Converters Based on Time-Domain Analysis of the State Observer Residual
(Institute of Electrical and Electronics Engineers, 2018-07-05)
Fault-tolerance capability is a critical matter in power conversion systems that require continuous operation. Multiphase converters provide an inherent redundancy that gives them fault-tolerant capability. In addition, ...
Fault diagnosis in grid-connected PV NPC inverters by a model-based and data processing combined approach
This paper presents a fault detection and isolation (FDI) method for open-circuit faults (OCF) in the switching devices of a grid-connected neutral-point-clamped (NPC) inverter for photovoltaic (PV) applications. The ...
Fault diagnosis on electrical distribution systems based on fuzzy logic

A Model-Based Strategy for Interturn Short-Circuit Fault Diagnosis in PMSM
(Institute of Electrical and Electronics Engineers, 2017-09)
A model-based method for interturn short-circuit fault detection and isolation in permanent magnet synchronous machines (PMSMs) is proposed in this paper. The fault detection is realized based on a residual current vector ...
On-Line Model-Based stator fault and identification in induction motors
(Institute of Electrical and Electronics Engineers, 2009-11)
In this paper, a model-based strategy for statorinterturn short-circuit detection on induction motors is presented. The proposed strategy is based on the generation of a vector of specific residual using a state observer. ...
Hybrid model for fault detection and diagnosis in an industrial distillation column
(De Gruyter, 2020-07)
The present work describes a method of automatic fault detection and identification based on a hybrid model (HM): First Principles – Neural Network. The FPM can simulate a wide range of situations while the NN corrects the ...
