A Generalized Power-Based Modelica Library with Application to an Industrial Hydraulic Plant

Abstract

This contribution presents a Modelica implementation of the generalized power-based modeling approach conforming to the bond graph methodology. The corresponding developed library BondGraph is discussed in detail. It allows graphical modeling according to the bond graph formalism, and contains common bond graph elements, as well as specific nonlinear elements, especially related to hydraulic effects. Furthermore, several composed models are provided, such as switching valves, pipes, cylinders, etc. A combination with blocks of the Modelica Standard Library is possible. The application of BondGraph to an industrial plant is described to demonstrate its capabilities.
