Abstract: Disclosed is a method for controlling a refrigerator including a motor driving a compressor. The method for controlling a refrigerator includes: identifying driving revolutions per minute (RPM) for driving of the motor; performing a control of temperature in the refrigerator based on the identified driving RPM; and storing operation information of the motor associated with the performing of the control of temperature, where the identifying of the driving RPM involves identifying stored operation information of the motor associated with a previous motor driving process.
