Detection of Additive and Multiplicative Faults - Parity Space vs. Parameter Estimation
Thomas Höfling,Thomas Pfeufer +1 more
TL;DR: In this article, the parity space approach with adaptive thresholds and the parameter estimation is used to detect and identify additive or multiplicative faults in a d.c.motor, and a combination of both methods is proposed to achieve optimal fault detection.

Incipient fault detection and identification in process systems using accelerated neural network learning
TL;DR: The objective of this paper is to present the development and numerical testing of a robust fault detection and identification system using artificial neural networks (ANNs), for incipient (slowly developing) faults occurring in process systems.
Proceedings ArticleDOI
Fault detection with model parameter structured uncertainties
TL;DR: This paper focuses on an original fault detection method, able to take into account parameter uncertainties described by bounded variables, based on the parity space approach, and stresses on the problems caused by dependencies between interval variables.

Data-Driven Schemes for Robust Fault Detection of Air Data System Sensors
TL;DR: A complete semiautomated data-driven approach is introduced to select the model regressors, to identify NARX input–output prediction models, to set up robust fault detection filters and to compute fault detection thresholds.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.

Parameter estimation for continuous-time models-A survey
TL;DR: The paper reviews the progress of research on parameter estimation for continuous-time models of dynamic systems over the period 1958-1980 and includes a classification system which conforms as closely as possible to that which has arisen naturally over the past two decades.
