Fuzzy-control design and realization of fresh air conditioning system

The fresh air conditioning system exchanges the air indoor with the fresh air outdoor which can adjust the temperature indoor and improve the quality of the air. In this paper, a fresh air conditioning experimental platform has been built according to the measurement and control demand of air conditioning system firstly. Then, according to the temperature data of different measurement ports that achieved by a large amount of experiment, the operating mode and the control characteristics has been summed up. Finally, a intelligent fuzzy control system has been designed for fresh air conditioning system which determines a fuzzy sets of input variables and the output variables of fuzzy control, a domain and a fuzzy control rule, which has realized automatic control goals of the fresh air conditioning system.
