Control strategies for an advanced aircraft-cabin temperature-system
Alexander Pollok · 2017 IEEE Conference on Control Technology and Applications (CCTA) · 2017
Thermal regulation of aircraft cabins requires controlling the temperature of supplied fresh air. State of the art plant architectures support only a small number of temperature zones. In this paper we consider a novel architecture that allows an arbitrary number of temperature zones. This is bought at the expense of a more complex control problem. Control challenges connected to this novel architecture are identified and possible control approaches are presented. They are benchmarked against high-fidelity models in the equation-based object-oriented modelling language Modelica. Results show that control input normalization offers significant advantages for any kind of control system, while the choice between PID-based and LQG-based control is somewhat ambiguous: The former shows better performance in the nominal case, the latter exhibits better robustness.
