Disclosed is a temperature control method which includes acquiring temperature data of a plurality of temperature detection points in a target environment; calculating, according to the temperature data, an average temperature value of the plurality of temperature detection points and a first temperature difference between the average temperature value and a target temperature value; determining whether an absolute value of the first temperature difference exceeds a first temperature difference threshold; and in response to the absolute value of the first temperature difference exceeding the first temperature difference threshold, controlling the temperature of the target environment by a variable universe fuzzy proportional integral derivative control algorithm.
