Analyse structurelle de réseaux de capteurs pour la commande et l'observation

Abstract : In this work, we are interested in sensor location and classification problems for control and observation of dynamical systems. When a considered property of the system is not satisfied with the initial set of sensors, we seek to implement additional sensors to make this property true. When a property is satisfied with the existing sensors, these sensors are classified into different categories according to their importance for the preservation of this property. We determine the critical sensors whose failure implies the property loss and the useless sensors which can fail without impact on the property. To study these two problems, we use the structured system approach with the associated directed graphs. Structured linear systems are a particular class of linear systems where the elements of state matrices are either zero or free parameters. With this approach, we study the problems of location and classification of sensors for disturbance rejection by measurement feedback and fault detection and isolation. The results are given in graphic terms. Keywords: Structured linear systems ; Structural analysis ; Sensor location ; Sensor classification; Disturbance rejection ; Fault detection and isolation.
