Application of self-adaptive fuzzy PI control in the air-conditioning system

The practical performance of the controller in the air-conditioning system is very important to the whole system. Although the traditional PID controller is widely used in a variety of industrial production situations and has achieved successful applications, it is only suitable for the analysis and design of the linear system, and it's unable for the analysis and design of the air-conditioning system which is time-delay and nonlinear. In this paper, a self-adaptive fuzzy PI control strategy is proposed to be used in the air-conditioning system. Simulation results and the practical control effect prove that the compound control structure possesses better performance than the conventional control method and satisfactory effects have been obtained.
