Abstract :
The air conditioner system is a nonlinear system with multi-interference, close coupling parameters, changefully working conditions and high inertia. Therefore, it´s difficult to achieve optimal results by using a simple control method. Based on the principle of heat transfer, this paper analyzes the room temperature change, establishes the mathematic model of air-conditioned room temperature, and puts forward a practical fuzzy-PID control strategy. This intelligent controller is implemented by MCU easily, and the simulation results verify that the controller has good performance.
