An XML Representation of DAE Systems Obtained from Modelica Models

摘要

This contribution outlines an XML format for representation of flat Modelica models. 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. Several such usages arise in the area of control engineering, where Linear Fractional Transformations (LFTs), derivation of robotic controllers, optimization, and real time code generation are some examples. The choice of XML is motivated by its defacto standard status and the availability of free and efficient tools. Also, the XSLT language enables specification of transformation of the XML model representation into other formats.
