Dynamic system simulation of an aircraft cabin climate for comfort-improved climate control

Knigge, H. / Joos, A. / Schmitz, G.

In cooperation with the Airbus Deutschland GmbH the Hamburg University of Technology (TUHH) participates in the German national funded project KATO (TP07 'Komfortverbesserte Klimaregelung'). One of the goals of this project is to model the inside of an Airbus A340 fuselage using dynamic system simulation in such a way that it can serve as a control path for advanced controller design. A model library is currently under development using the modeling language Modelica. This library can be used for the setup of simulation models, that describe the thermo-pneumatic conditions in the pressurized fuselage. An adequate simulation model including heat flux, mass flow and momentum balance will be provided, which will serve as a control path, both for the computer-assisted controller development and for 'hardware in the loop' applications. The Modelica simulation environment (Dymola [3]) used for this task offers the possibility, to export models through an interface to the software Matlab/Simulink [7]. Here they can provide a basis for controller optimization tools, e.g. MOPS [4], or can be integrated into control loops. By using this method, new control techniques and control concepts can be tested quickly and economically.
