Modular and Multi-view Representation of Complex Hybrid systems

Abstract:- A modular and multi-view approach for the modelling of complex hybrid systems is presented. The aim is to define a global representation of this class of system, i.e. a representation which groups together in a same structure several types of information coming from different origins. Such a model, used for different purposes like the simulation of the process or the diagnosis, constitutes a first step toward an objective of supervision of the plant. For that a decomposition of the process based on the notion of input-output blocks is examined, and a hybrid generic object is then deduced. The modular building of the plant model from this object is shown, as the way to consider this plant under different aspects. The approach is illustrated for simple examples coming from the chemical engineering area.
