Abstract :
We propose in this paper a graphical interpretation of the structural properties of a system. The concerned properties are the observability, the controllability and the reconfigurability. The observability allows to identify the part of the system which is monitorable and the controllability allows to drive the system to a wished state. These two properties are required for the realisation of the system objectives. The reconfigurability analysis aims to decide whether the system remains observable and controllable when a part of system components becomes faulty. A graphical approach is used to analyze these properties from a structural point of view. The different notions are illustrated on a two tank process example
