Abstract

The invention discloses an air conditioner intelligent control method and system based on fuzzy reasoning. The air conditioner intelligent control method comprises the steps that input parameters and output parameters of an air conditioner are obtained; the input parameters and the output parameters are converted into fuzzy sets through a membership function correspondingly; a fuzzy rule base is constructed; reasoning operation is conducted on the fuzzy sets according to a fuzzy rule of the fuzzy rule base; deblurring operation is conducted on the reasoning operation result; and according to the deblurring operation result, the input parameters of the air conditioner are adjusted, and control over the air conditioner is achieved. The indoor environment temperature is represented through a fuzzy language, an accurate control scheme is obtained through the steps of fuzzification of accurate parameters, fuzzy rule construction, fuzzy reasoning, deblurring and the like, and an air conditioning system is controlled to accurately adjust the environment temperature. The air conditioner intelligent control method and system overcome the defects that a traditional air conditioner control algorithm is hysteretic and not accurate in adjustment parameter, and a more comfortable home environment is provided for a user while energy is saved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to an intelligent air-conditioning control method and system based on fuzzy reasoning. Background technique [0002] The statements in this section merely mention the background technology related to the present invention and do not necessarily constitute the prior art. [0003] With the progress of society and the improvement of people's living standards, air conditioners have become an indispensable part of people's life and work. The control of the air conditioner on the ambient temperature directly affects people's quality of life. Therefore, how to accurately control the temperature parameters of the air conditioner controller and solve the adverse characteristics of the control process, such as sudden change and hysteresis, has always been a problem studied by scholars. Today, most air conditioners still use PID controllers for process control. This control m...
