Automatic generation of supervision system based on bond graph tool

Abstract

The paper deals with an integrated approach for supervision systems design based on a mechatronic properties of a bond graph tool. The methodology is implemented in a specific software which automatically creates complex process dynamic models from a simple graphical interface, where system components can be dragged from a component data base and interconnected so as to produce the overall system, following the Piping and Instrumentation Diagram. Once the model has been created, the software checks its consistency and performs its structural analysis in order to automatically determine the diagnosis algorithms which should be implemented, and their fault detectability and isolability performances. The friendly graphical user interface allows to test several sensor configurations in order to optimise the diagnostic possibilities. The obtained model can also be used for the simulation of the process and its diagnosis algorithms in normal and faulty situations.
