Switching systems mode estimation using a model-based diagnosis method
Résumé
Switching systems are a particular class of hybrid systems. They are represented by several operating regimes, called modes, each of them being active under certain particular conditions. The modes can be associated with normal or faulty operating conditions. Therefore, the determination of the active mode at any moment constitutes a fault diagnosis approach for such systems. This paper addresses the issue of the determination of the active mode at any moment, using only the system's input/output data. To perform this task, we propose an adaptation of the well-known parity space method to this class of system. Conditions that guarantee the uniqueness of the determined active mode are also given.
