A Novel Approach for Handling Discontinuities in Non-iterative Co-simulation

Abstract

In this work, a novel approach for the co-simulation of systems with discontinuities is presented. Currently, an extensive literature exists on the simulation of distributed systems as well as on the proper discontinuity handling during simulation. The not trivial task is to design a simulation platform that is able to do both at the same time. The proposed algorithm, which extends an existing non-iterative co-simulation strategy, administrates the mutual communication between two subsystems to assure that events are propagated correctly within the distributed system. Based on a prediction of future event triggering, the co-simulation sequence is chosen and thus the discontinuities are handled with no need of "rolling-back" or of iterating. A simulation example demonstrates the efficiency of the outlined algorithm.
