Because working environment of ICCTC is complex,it is difficult to control the temperature and humidity. An intelligent control system of ICCTC was designed to adjust temperature and humidity of the chamber during the test. An expert controller was designed to regulate temperature,and a fuzzy controller was designed to regulate the humidity in the chamber. Since the chamber was closed, the temperature change would affect the humidity,so the system also used a decoupling control strategy. The practical application results show that the system is reliable and the control accuracy is high.
