Physical Modeling
We build simulation models of mechatronic and in particular of automotive systems. QTronic has years of experience in modeling automatic transmissions to support control development for such systems. Our references include modeling of a dual clutch transmission for sports car maker AMG using the multi-domain modeling language Modelica.
Modeling language Modelica
Modelica is a vendor-neutral language for object-oriented modeling of physical systems. Modelica has been developed since 1997 by the non-profit Modelica Association (http://www.modelica.org). Good quality simulators for Modelica are offered by several providers. Due to its multi-domain concepts, Modelica offers outstanding support for the modeling of mechatronic systems.
Benefit for the development process
- Only one language: All physical sub-systems, from differing engineering disciplines, can be conveniently modeled with one language. This minimizes the overhead for training and tool integration.
- Reuse: Modelica offers outstanding support for the reuse of models and model components. This often leads to a dramatic reduction of labor costs and time for model creation.
- Tool independence: A Modelica model can be processed by any Modelica tool, such as Dymola, SimulationX, or even free tools such as JModelica or OpenModelica. This helps to secure your investment in models and model libraries.
- Maintainability: With Modelica, local changes of a system cause only local changes in the corresponding model, due to Modelica's equation-based approach. This distinguishes Modelica from block-oriented languages and simplifies maintenance of Modelica models significantly.
