| Approach |
Modeling of power resp. energy flows - as an alternative regarding the use of signal flow diagrams.
Further members of this tool family for alternative modelling are e.g. Power Oriented Graph
(POG) and
Energetic Macroscopic Representation
(EMR).
All three methods can work with the same parameter definitions,
but focus on different aspects of the dynamic system. |

| Gain |
Symbolism independent of energy domains; preservation of physical structures - contrary to
transfer functions as computation structure; direct definition of graphical models even for
simulations and without previous determination of diffential equations; easy determination
of diffential equations based on bondgraphs in comparison with use of d'Alemberts principle
or Lagrange equations; better effectiveness (component based design) and efficiency (better
productivity) regarding modelling process |
