Using FMI components in discrete event systems

The simulation of hybrid system is of interest in different areas, e.g., cyber-physical energy systems. This includes the embedding of continuous-time subsystems in discrete event systems. The difficulties of resulting synchronisation schedules are approached by precalculation within the components. The Functional Mock-up Interface (FMI) is a state of the art specification for the co-simulation of continuous systems, which is supported by a growing number of simulation software. FMI for Model Exchange components generated with OpenModelica have been embedded in the discrete event domain of Ptolemy II as a proof of concept. An example shows that the use of FMI components has a better scalability and shorter runtime than a pure Ptolemy II implementation.
