Problems solved by technology

However, since the fuzzy control rules cannot be infinitely subdivided, the simple use of fuzzy control methods often leads to poor steady-state control accuracy and steady-state errors.

Abstract

The invention discloses an air conditioner control method, an air conditioner control device and an air conditioner. The control method includes the steps that the indoor environment temperature and the outdoor environment temperature are detected; the difference value delta T between the indoor temperature and the temperature set by a user is computed; the operating time of the air conditioner is detected; when the operating time is smaller than a preset time, the fuzzy control coefficient of a compressor is computed according to the difference value delta T, the outdoor environment temperature and a preset fuzzy control rule, and the operating frequency of the compressor is computed according to the fuzzy control coefficient; and when the operating time is larger than or equal to the preset time, the operating frequency correction value of the compressor is computed according to the difference value delta T and a preset PI control model, and the operating frequency correction value is added to the operating frequency to control the compressor to operate according to the corrected operating frequency. According to the control method, fuzzy control and PI control are combined to control the compressor so that the compressor can achieve a better control effect; and the precision of steady control is guaranteed and the steady state error is eliminated while the higher response speed is achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner control method, an air conditioner control device and an air conditioner with the air conditioner control device. Background technique [0002] Under the conditions of indoor temperature control, the inverter air conditioner usually achieves the purpose of energy saving by changing the operating frequency of the inverter compressor. In related technologies, the following two control methods are generally used to control the inverter compressor of the air conditioner: [0003] One is the traditional PID (proportion-integration-differentiation, proportional-integration-differentiation) control method. This air-conditioning control method often requires the establishment of a mathematical model of the air conditioner first, and the relationship between the set temperature input by the user and the indoor temperature Differentially adjust the working f...
