1. An aerosol generating device comprising:
a heater configured to generate an aerosol by heating an aerosol generating substrate;
a storage unit configured to store information regarding a first time period, a second time period and third time period for controlling a temperature of the heater;
a controller configured to control power supplied to the heater,
wherein the controller,
when the temperature of the heater reaches the first target temperature and the first time period elapses, changes the temperature of the heater to the second target temperature over the third time period and maintains the second target temperature for the second time period, and
the sum of the first time period, the second time period, and the third time period is a time period in a preset range.
