Compositional Modelling of Hydrodynamic Plants in Simulink∗

In this work, we report on efforts for building a prototype simulink library for compositional modelling of hydrodynamic networks. The work is inspired by a cooperation with the EDF, where the desire for compositional modelling in a causal framework was exposed. The nature of the dynamics of hydrodynamic systems itself is compositional, and it is desirable to profit from this compositionality for modelling. This can be of great importance for quick production of prototype simulation models for understanding system dynamics. We explain the modelling technique used and how it relates to other approaches, give examples to indicate the construction of the prototypic simulink library and comment on experiences gained with this model.
