Fault Detection and Isolation Filter Design by Inversion: The Case of Linear Systems
TL;DR: In this paper, a new filter design method based on weak failure observability and weak failure separability conditions is proposed for fault detection and isolation in the Luenberger filter design, where the (C, A)-invariance is completely ignored.

Modelling of uncertainties for robust fault diagnosis
TL;DR: In this article, the authors present new methods for determining the structure of modeling uncertainties based on deconvolution of unknown inputs, and several theoretical conditions are discussed, and a jet engine system is used to illustrate the method.
