Abstract
The simulation of cyber-physical systems involves the handling of modular and heterogeneous systems. This often involves the embedding of continuous-time based subsystems in a discrete event-driven system, for which most conventional approaches enforce restricting synchronization schedules. The approach presented here uses state predictions for each individual continuous subsystem to overcome this limitation. This allows continuous subsystems to be treated as ordinary discrete components within a discrete event system, without restrictions on the synchronization schedule. This concept has been implemented in the FMI++ library, that operates on top of the Functional Mock-Up Interface for Model Exchange (FMI ME) specification and utilizes its basic functionalities to interact dynamically with the encapsulated continuous model. A proof of concept simulation is presented where continuous time-based OpenModelica models are embedded into the Discrete Event domain of Ptolemy II. This is compared to an analogous model implemented in Ptolemy II only.
