An XML representation of DAE systems obtained from continuous-time Modelica models

In English This contribution outlines an XML format for representation
of differential-algebraic equations (DAE) models obtained from
continuous time Modelica models and possibly also from other
equation-based modeling languages. The purpose is to
offer a standardized model exchange format which is
based on the DAE formalism and which is neutral with
respect to model usage. Many usages of models go
beyond what can be obtained from an execution interface
offering evaluation of the model equations for
simulation purposes. Several such usages
arise in the area of control engineering,
where dynamic optimization, Linear Fractional Transformations (LFTs),
derivation of robotic controllers, model order reduction, and real
time code generation are some examples. The choice
of XML is motivated by its de facto standard status
and the availability of free and efficient tools. Also,
the XSLT language enables a convenient specification of
the transformation of the XML model representation into other
formats.
