1. A method of controlling an aerosol generating device, the method comprising:
measuring a current temperature of a heater before power is supplied to the heater that heats an aerosol generating material;
adjusting a preset preheating completion parameter, based on the measured current temperature of the heater and a value of an amount of heat required to be supplied to the aerosol generating material to generate an adequate amount of aerosol; and
controlling power supplied to the heater, based on the adjusted preset preheating completion parameter, such that a value of an amount of heat supplied to the aerosol generating material by the heater reaches the value of the amount of heat required to be supplied to the aerosol generating material,
wherein the preset preheating completion parameter comprises at least one of a preheating completion temperature and a preheating completion time, and
wherein the adjusting the preset preheating completion parameter is performed before a user's puff on the aerosol generating device is detected.
