Fault detection model‐based controller for process systems
TL;DR: In this paper, a model-based control system for fault detection and controller reconfiguration using stochastic model predictive control (MPC) is proposed, which can determine online the optimal control actions, detect faults quickly, and reconfigure the controller accordingly.

A two-ellipsoid overlap test for on-line failure detection
TL;DR: The implementation of a necessary and sufficient condition is shown to result in a scalar test which does not call for any optimization procedure and so offers the advantage of low computational expenditure.
Journal ArticleDOI
Multivariate Statistical Approaches to Fault Detection and Isolation
TL;DR: These approaches, based more around the concepts of multivariate statistical process control are fundamentally different from the analytical redundancy approaches used in much of the FDI literature.
Proceedings ArticleDOI
Fault Detection and Isolation of Industrial Processes Using Optimized Fuzzy Models
TL;DR: A modification to the regularity criterion algorithm is proposed, aiming the reduction of computational time without loss of accuracy, and the fuzzy models obtained using the modifiedRegularity criterion algorithms are optimized by a real-coded genetic algorithm.

Multipass Optimal FIR Filtering for Processes With Unknown Initial States and Temporary Mismatches
TL;DR: It is shown that the DOFIR and TOFIR filters are able to essentially improve the performance close to the initial values and are more robust against temporary model mismatches than the Kalman, OFIR, and UFIR filters.

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.
