TL;DR: The DAMADICS European Research Training Network (DAMADICS) actuator benchmark used in fault diagnosis studies is described in this paper, which is based on an in-depth study of the phenomena that can lead to likely faults in valve actuator systems and includes typical engineering requirements of an actuator valve operating under challenging process conditions, e.g. providing a set of performance indices for evaluating the results.

TL;DR: It is shown that the algorithms proposed to tackle the above tasks make it possible to obtain a suitably accurate mathematical description of the system that allows developing a technique of generating an adaptive threshold that permits robust fault detection.
115 citations
TL;DR: A new framework for fault detection and isolation (FDI) based on neuro-fuzzy multiple modelling together with robust optimal de-coupling of observers is presented and a comparative study of NFDFDS with the Extended Unknown Input Observer (EUIO) is provided.

TL;DR: A procedure is proposed for controlling a system over a network using the concept of an NCS-information-packet which is an augmented vector comprising control moves and fault flags which defines a completely fault tolerant NCS.
Abstract: This paper deals with fault-tolerant control of a network controlled systems (NCS) problem, where the sensors, actuator and controller are inter-connected via a communication network. A procedure is proposed for controlling a system over a network using the concept of an NCS-information-packet which is an augmented vector comprising control moves and fault flags. The size of this packet is used to define a completely fault tolerant NCS. The behavior and control of this scheme is illustrated by way of an example, where the plant is being controlled over a network. Implicit in this paper is that appropriate FDI schemes exist within the set up. The software environment used is MATLABcopy and LABVIEWcopy. The results illustrate that the scheme is tolerant to faults.

TL;DR: In this paper, a wavelet neural network with local recurrent structure and its application to fault detection and isolation (FDI) of components of a dynamic process was investigated, where a neural simplified observer scheme was used to generate the residuals (symptoms) in the form of one step-ahead prediction errors.

TL;DR: In this article, an active fault-tolerant control (FTC) scheme based on gain-scheduled H-infinity controller and neural network is proposed, which is used for successful FTC control of a double inverted pendulum system with a fault in the tachometer loop of the motor.
TL;DR: In this article, the authors describe the reliability and performance evaluation of fault detection and isolation (FDI) for the attitude control of a typical satellite, the Mars Express (MEX) orbiter.
TL;DR: In this paper, a new dynamic neuro-fuzzy system and its application to fault detection and isolation of an evaporation station from a sugar factory is presented. But the authors only used a single sensor and actuator.
