ZoneLib: A Simulink Library for Modeling Zone Divided Climate Dynamics

摘要

We present a dynamic model for climate in a live-stock building divided into a number of zones, and a corresponding modular Simulink library (ZoneLib). While most literature in this area consider air flow as a control parameter we show how to model climate dynamics using actual control signals for the ventilation equipment. To overcome a shortcoming in Simulink to solve algebraic equations and matrix inversions, we have developed the library inspired by the so called dynamic node technique. We present simulation results using the presented library, and concludes with visions for further development of ZoneLib.
