Détection et localisation des défauts des capteurs

Abstract

This thesis deals with a method for detection and isolation sensors faults on a dynamic linear time-varying system. This method consists in estimating the faults magnitude thanks to a least square module coupled to the Kalman filter estimating the system state. The proposed approach allows considering additive and simultaneous faults.

Keywords: detection, localization, faults, drifts, sensors, estimation, Kalman filter, least squares, dynamical systems.
