TL;DR: The methods, which are mainly of algebraic flavour (module theory, differential algebra, and operational calculus), are borrowed from recent works on control and identification, and it is hoped that the results might be understood by a large community.
Abstract: We are generating residuals for linear fault diagnosis and isolation which are 1. robust with respect to a large variety of additive disturbances, A reader who is already familiar with this algebraic setting may directly proceed to § 3. The numerous examples on various aspects of diagnosis, like the previous one, are written on the other hand in such a way that they may be understood by anyone who is not mastering those mathematical tools. We hope therefore that our results might be understood by a large community. 2. working in closed-loop, even with uncertain parameters. Several examples with their computer simulations, including a concrete case-study of a two mass system, are enlightening our viewpoint. Our methods, which are mainly of algebraic flavour (module theory, differential algebra, and operational calculus), are borrowed from recent works on control and identification.

Journal ArticleDOI
TL;DR: In this paper, the analysis and compression of noisy transient signals are handled via methods stemming from elementary differential algebra, noncommutative algebra and operational calculus, and the efficiency of their approach is illustrated by an academic example and a more concrete case-study which is a musical signal.

Journal ArticleDOI
TL;DR: In this article, an approach for Fault Tolerant Control dealing with critical fault is proposed in which the aim is to preserve after fault occurrence the ability for the degraded system to reach performances as close as possible to those which were initially assigned to the system.
