Modelling the robustness properties of HVAC plant under feedback control


A lumped capacitance model was developed in Matlab/Simulink to simulate HVAC plant and control. Construction elements were modelled using an equivalent electrical resistance-capacitance ( R-C ) circuit, the resistance and capacitance values being established using optimisation techniques. A model of a room space with hot water radiators for heating and a chilled ceiling system for cooling was developed to analyse control system response. The resulting model was flexible, transparent and exhibited good computational efficiency. 14 refs.
