Présentation de l’utilisation de modèles de défauts d’un système pile à combustible pour le diagnostic.
Abstract—This paper is concerned with the conception and study of faulty and faultless models of a fuel cell system. Due to the interaction between many components, a fuel cell system is a complex system where faults can occur and cause hard damages not only to the stack but also to the system environment. In this paper, we present an approach to integrate faults in a model of a fuel cell system ; then we define a technique for the diagnosability study of faults from these models. This technique uses temporal formulas, adapted from the metric interval temporal logic, to characterize observable behaviors of the system in the faultless and all faulty cases. These fault characterizations will be then embedded inside the diagnosis system in order to detect and identify faults on line and without any ambiguity.
