The object-oriented multi-domain language Modelica has been applied very successfully in some prominent Aerospace projects such as POA or MOET und proved to be an adequate tool to describe heterogeneous energy systems consisting of electrical, electronic, hydraulic, pneumatic, thermo-dynamical and mechanical components.
Regarding the DLR project “Next Generation Train” the department of System Dynamics and Control cooperates with the DLR Institute of Vehicle Concepts in the NGT work package Energy-Management providing methods and tools support in particular regarding high level analysis methods like optimisation, anti-optimisation, uncertainty-modelling and Monte-Carlo-Simulation.
In May 2008, the FP7 project Sympass, in which the institute took the lead for the work-package System Simulation Platform, was approved by the EU commission and started. The project was supposed to develop a simulation environment for the complex auxiliary power system in railway vehicles together with its onboard control system called TCMS. The environment should be open to hardware-in-the-loop and software-in-loop applications, see figure below.
