Abstract

Room air temperature controlling of single zone space was studied in this paper. Firstly, a mathematical model of temperature-controlling was built for fresh air conditioning system of the solar energy with LHTS. Then, a fuzzy-PID controlling method was put forward and applied to control the indoor temperature according to the features of high nonlinearity, large disturbance and uncertainty of the VAV air conditioning system. The parameters of PED can be adjusted online with the help of fuzzy control. It is proved that the fuzzy-PID control, owning the advantage of fuzzy control and PID control, can improve controlling effect of complicated controlling system with simple steps.
