Mechatronic systems as well as other technical systems (microsystems, distributed automation systems, ...) can be characterized as complex heterogeneous systems. Typically, they show some of the following features:
- mixed physical domains (mechanical, electrical, thermal, fluidic, ... phenomena),
- partially close coupling between these domains,
- distributed and lumped effects or elements, respectively,
- continuous and discrete signals and systems(in electronics: analog and digital).
Often, the modeling of continuous systems leads to very large systems of stiff differential equations. In contrast, system simulation requires simpler and faster models to investigate the interaction between all components. That's why a powerful methodology for the modeling and simulation of mechatronic systems is demanded which considers their special characteristics. This methodology must cover a unified modeling approach, standardized modeling languages, algorithms and tools for model generation and capabilities for system optimization. In the following an approach for modeling is presented which meets these requirements. A real-world example, the modeling of an elevator system, shows the application of the modeling approach.
