摘要：
The temperature and humidity decoupling control method was presented in this paper to resolve the coupling problem between temperature and humidify in central air-conditioning variable dew point control system. By introducing absolute humidity as an intermediate variable to control the machine dew point, temperature and humidify of system can be decoupled. Two input and two output transfer function model was established by combining the theoretical analysis with the data analysis of experiment, and a control system consisting of a feed forward compensation decouple control and PID control was designed. The simulation based on MATLAB results demonstrated that this method is effective, and is also effective to control temperature and humidity system.
