Design of observers for TakagiߝSugeno descriptor systems with unknown inputs and application to fault diagnosis
TL;DR: In this paper, a method for state-estimation of Takagi-Sugeno descriptor systems (TSDS) affected by unknown inputs (UI) is presented, where the proposed observers are not in descriptor form but in usual form.
Journal ArticleDOI
Brief paper: state estimation of Takagi-Sugeno systems with unmeasurable premise variables
TL;DR: In this paper, the design of observers for non-linear systems described by Takagi-Sugeno (T-S) multiple models with unmeasurable premise variables is studied.
Journal ArticleDOI
An improved PCA scheme for sensor FDI: Application to an air quality monitoring network
TL;DR: In this article, a sensor fault detection and isolation procedure based on principal component analysis (PCA) is proposed to monitor an air quality monitoring network, which is optimal with respect to a reconstruction error criterion.

Journal ArticleDOI
Fault Detection and Isolation with Robust Principal Component Analysis
TL;DR: In this paper, a fast two-step algorithm is proposed for fault detection and isolation based on robust principal component analysis (PCA) which is applied to remove the effect of outliers on the PCA model.
