An Intelligent Fault Detection Model for Fault Detection in Photovoltaic Systems [PDF]
Journal of Sensors, 2020 Effective fault diagnosis in a PV system requires understanding the behavior of the current/voltage (I/V) parameters in different environmental conditions. Especially during the winter season, I/V characters of certain faulty states in a PV system closely resemble that of a normal state.

The Fault Detection Problem [PDF]
, 2009 One of the most important challenges in distributed computing is ensuring that services are correct and available despite faults. Recently it has been argued that fault detection can be factored out from computation, and that a generic fault detection service can be a useful abstraction for building distributed systems.

Model-based fault detection and isolation for wind turbine [PDF]
, 2012 In this paper, a quantitative model based method is proposed for early fault detection and diagnosis of wind turbines. The method is based on designing an observer using a model of the system. The observer innovation signal is monitored to detect faults.

General computational approach for optimal fault detection [PDF]
, 2009 We propose a new computational approach to solve the optimal fault detection problem in the most general setting. The proposed procedure is free of any technical assumptions and is applicable to both proper and non-proper systems.

On parametric solution of fault detection problems [PDF]
, 2011 We discuss the solution of the fault detection problem in presence of parametric uncertainties. The basic approach is an extension of the nullspace method for constant systems to the case of linear parameter varying (LPV) models.

A change-detection algorithm for short-circuit fault detection in closed-loop AC drives [PDF]
, 2013 This paper deals with an on-line method for turn-to-turn short-circuit fault detection in low-voltage permanent-magnet synchronous machine drives. Due to the closed-loop control, the fault effects are reflected in the voltage.

Fault detection and diagnosis of a plastic film extrusion process [PDF]
, 2010 This paper presents a new approach to the design of a model-based fault detection and diagnosis system for application to a plastic film extrusion process. The design constructs a residual generator via parity relations.
