| Résumé: | In this paper, we consider the optimal sensors placement problem for
faults detection and isolation using a novel structural and qualitative approach. This
approach is based on the conversion of Bond Graph to Digraph representation of
a structural system. When the fault detection and isolation of an existing system’s
sensors are impossible or uncertain, a reconfiguration sensor placement of this system
should be reconsidered. This paper proposes how this reconfiguration takes place
by recovering all missing or redundant parts of the system. This novel approach is
illustrated over a thermo-fluid application |
