摘要：This paper deals with the problem of controlling greenhouse environment defined by the temperature andhumidity. According to the thermal balance principle and water vapour quality balance principle of greenhouse,two non-linear differential models each for air temperature and humidity inside greenhouse were constructed.The corresponding fuzzy controller for greenhouse environment was set up by using the ANFIS tools ofMATLAB, including the choosing of variables, quantification of the domain, definition of fuzzy sets, choosingof membership functions and controller training. After the combination between controller and the controlledobject by Simulink, simulation was carried out to analyse the performance of control system. The simulationresults testify the validity and reasonability of the fuzzy control strategy for the environment control in thegreenhouse, and the achievement has certain reference value for the development in intelligent control of thegreenhouse microclimate.
