Modeling of the heating system in small building for control

Model identifications for the heating system of small building are presented. Basic problems of data acquisition and preprocessing are detailed. Specially designed wire-less data collection and control system to conduct real-world experiments are described. The model structure choice based on analysis of weather condition influences on the system performance are presented. Finally, the general structure of two-layered heating control strategy for the heating system is proposed. Instead of heating, ventilating and air conditioning (HVAC) standard, the proposed strategy controls only indoor temperature and changes the set point according to additional measurements of indoor humidity to keep thermal comfort. Non-linear compensation of outdoor temperature and wind speed is also introduced.
