Fault Detection for Uncertain Fuzzy Systems: An LMI Approach
TL;DR: This paper studies the problem of designing a robust fault-detection system for uncertain Takagi-Sugeno fuzzy models and the worst case fault sensitivity measure is formulated in terms of linear matrix inequalities.
Journal ArticleDOI
Incipient fault diagnosis of dynamical systems using online approximators
TL;DR: A general framework for model-based fault detection and diagnosis of a class of incipient faults is developed and an automated fault diagnosis architecture using nonlinear online approximators with an adaptation scheme is designed and analyzed.

A Multidimensional Critical State Analysis for Detecting Intrusions in SCADA Systems
TL;DR: This paper presents an innovative approach to Intrusion Detection in SCADA systems based on the concept of Critical State Analysis and State Proximity, and the theoretical framework is supported by tests conducted with an Intrusions Detection System prototype implementing the proposed detection approach.
Journal ArticleDOI
A New Fault Diagnosis Method Using Fault Directions in Fisher Discriminant Analysis
TL;DR: A new process monitoring method is proposed that is composed of a preanalysis step that first roughly identifies various clusters in a historical data set and then precisely isolates normal and abnormal data clusters by the k-means clustering method and a fault diagnosis method based on fault directions in pairwise FDA.

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.
