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 demonstrating capabilities of the library.
