Parameter Estimation of Dynamic Multi-zone Models for LivestockIndoor Climate Control

In this paper, a multi-zone modeling concept isproposed based on a simplified energy balanceformulation to provide a better prediction of theindoor horizontal temperature variation insidethe livestock building. The developedmathematical models reflect the influences fromthe weather, the livestock, the ventilation systemand the building on the dynamic performance ofindoor climate. Some significant parametersemployed in the climate model as well as theairflow interaction between each conceptualzone are identified with the use of experimentaltime series data collected during spring andwinter at a real scale livestock building inDenmark. The obtained comparative resultsbetween the measured data and the simulatedoutput confirm that a very simple multi-zonemodel can capture the salient dynamical featuresof the climate dynamics which are needed forcontrol purposes.
