Finite memory observer design for continuous-time nonlinear systems with discrete-time measurements: application to diagnosis

Autor: ZHANG, Tingting

Publikováno v: Automatic. INSA CVL-Institut National des Sciences Appliquées-Centre Val de Loire, 2021. English

The aim of this thesis is to design a nonlinear observer as a diagnostic tool for continuous-time nonlinear systems with discrete-time measurements. We begin with the study of some observability notions concerning the considered nonlinear systems, fo

Temporal framing of a finite memory observer for network control systems applied to measurement losses and integrity recovery

Autor: Thuillier, Julien, Delouche, David, Fantini, Jacques, Kratz, Frédéric

This paper focuses on a tool to estimate lost data on network control systems. The tool is also able to detect loss of data integrity and estimate the correct value. A new formulation of the Finite Memory Observer using a finite collection of measure

Fiabilité de l’intégrité des informations par observateur à mémoire finie pour un système commandé en réseau

Autor: Thuillier, Julien

Publikováno v: Automatique / Robotique. INSA Centre Val de Loire, 2019. Français

The works described in this thesis deal with the integrity and availability of networked control systems information. The importance of this has been highlighted by the growing number of cyber-attacks. A finite memory observer is proposed as a tool t

Finite memory observer for switching system: application to diagnosis

Autor: Hocine, Abdelfettah, Maquin, Didier, Ragot, José

Publikováno v: Workshop on Advanced Control and Diagnosis
Workshop on Advanced Control and Diagnosis, Dec 2004, Karlsruhe, Germany. pp.CDROM

International audience; In this paper, we develop a fault detection method for switching dynamic systems with unknown inputs. These systems are represented by several linear models, each of them being associated to a particular operation mode. The pr
