Abstract:

This paper presents a controller based on input-output linearisation (IOL) for a vapor compression cycle leveraging a moving-boundary model of the evaporator. After a presentation of the test rig and adaptations of a previously published high-order simulation model, the control-oriented moving-boundary model is derived. Special emphasis is laid on steady-state solutions of the governing partial differential equations. The corresponding ansatz functions enable a high model accuracy while keeping the model order low. The IOL based on the moving-boundary model is compared by simulations with a previously published IOL based on a lumped-parameter approach. Here, the IOL based on the moving-boundary model shows a high performance in a much larger operation range. These results can be confirmed through the comparative evaluation with experimental data. Finally, we show the general applicability of the controller with an implementation on a dedicated test rig at the Chair of Mechatronics, University of Rostock.
