Equation-Based Modeling with Modelica - Principles and Future Challenges

Modelica is a well-established, open standard for the modeling and simulation of cyber-physical systems. Since it is based on equations, this modeling language is applicable to a multitude of physical domains and especially suited for complex physical systems and their control. This paper provides a brief introduction on the kind of equation-based modelling promoted by Modelica and its underlying core principles. The paper then describes its current state in development and outlines the most important technology trends for its future development
