1. An aerosol generation device, comprising:
a load used to heat an aerosol generation article by using power that is supplied from a power source, the aerosol generation article comprising an aerosol-forming substrate configured to hold or carry at least one of an aerosol source and a flavor source; and
processing circuitry configured to
acquire a temperature of the load, and
control the power that is supplied from the power source to the load by feedback control, based on a difference between the temperature of the load and a predetermined temperature,
execute the feedback control so that the temperature of the load or the power supplied from the power source to the load increases over an entire use phase where the temperature of the load is equal to or higher than a value at which a predetermined amount or more of aerosol can be generated from the aerosol generation article,
when a drop of the temperature of the load is detected during execution of the feedback control, change a value of a variable that is used in the feedback control, so as to increase the power that is supplied from the power source to the load, and
change the variable to a value that is different from a value before the change based on detection of the drop, when the drop is resolved.
