Project description: Swedish industry is among the world leading on modeling of cyber-physical systems. By using high-level modeling languages like Modelica, complex physical systems can be modeled in a compact and natural way, reusing libraries for different engineering domains like mechanical, electrical, thermal, control, etc. Advancing this area is of great strategic importance. In this project, we focus on scalable techniques for performance, novel tooling, and for extending the application area to generating control software for cyber-physical systems.
Our research builds on open-source platforms for the Modelica language: OpenModelica and JModelica.org, and
open-source platforms for metacompilation: RML/MetaModelica and JastAdd. These systems are extended and
applied to demonstrate results in the form of new algorithms, tools, and language constructs. The project focuses
on aspects that support scaling to large applications, in particular performance, development support, and control
For large applications, performance becomes a bottleneck. To counter this, we will develop new techniques for
automated parallelization of compilation as well as simulation, using both data and control parallelism. The development of large applications requires advanced tooling for editing, debugging, and verifying models. We will develop novel tools with particular focus on interactive visual smart editing, equational debugging, and support for model requirements as well as testing and verification of requirements. Modeling is traditionally used for simulation, but extending their application to generate control software is an active research area. We will work on new language constructs for supporting the generation of embedded control software directly from models, for example in the form of FMUs (Functional Mockup Units). We will demonstrate the new results on large models in the order of 100k equations.
