Abstract

This paper discusses the cooperative simulation of models implemented in Modelica; Simscape; Simulink and MATLAB for the aim of energy optimization in cutting factories. To simulate the thermal processes in production halls; the machines and the room itself have to be modelled in varying detail. To achieve a quite accurate comprehensive model; the individual machines and the room are modelled in different software and then simulated with the co-simulation tool BCVTB. The communication between the individual models requires a lot of preparative work and as can be seen at the end of the paper; it works fine for a fixed communication time step but is not possible with a continuous synchronization for all given software. Still; the possibilities of co-simulation with BCVTB can be found sufficient for the needs of thermal processes which react very slowly and not in time steps of hugely differing dimensions respectively; but require a period of time which can easily be approximated small enough for a certain scenario.
