Designing of Temperature and Humidity Intelligent Control System Based on Temperature and Humidity Model in the Greenhouse

The greenhouse temperature and humidity accurate adjustment has huge influence on the growth of crops. The temperature and humidity model was analyzed in the Venlo greenhouse. According to some factors which affect on the changes of temperature and humidity in greenhouse,temperature and humidity adjustment control object was determined. The fuzzy PID control algorithm and hardware platform was designed. The control test of greenhouse in Jiangsu University is passed.
