Abstract: A pressure cooking apparatus, a method and device for controlling the same are provided. During a heating process of the apparatus, the device detects a pressure value inside the inner liner, a first temperature value when the detected pressure value rises to a first preset pressure threshold, and a second temperature value when the detected pressure value drops from the preset first pressure threshold to a second preset pressure threshold. Next the device acquires a temperature reference value according to a preset setting strategy using the first temperature value and the second temperature value and then compares a current temperature value detected by the temperature sensor with the temperature reference value. Finally, the device starts or stops the heating process based on the comparison result, thus reducing the on/off frequency of the apparatus and controlling the pressure inside the cooking apparatus more precisely and smoothly.
