Aerosol generation device, control method and storage medium

A control method of power that is supplied from a power source to a load, the load being used to heat an aerosol generation article comprising an aerosol-forming substrate configured to hold or carry at least one of an aerosol source and a flavor source, the control method comprising:

• starting supply of the power from the power source to the load;
• in a case of a use phase where a temperature of the load is equal to or higher than a value at which a predetermined amount or more of aerosols is capable of being generated from the aerosol generation article, acquiring the temperature of the load and a degree of progress of the use phase;
• executing feedback control so that the temperature of the load converges to a predetermined temperature;
• and
• increasing a gain in the feedback control or an upper limit value of the power that is supplied from the power source to the load, as the degree of progress progresses, in the feedback control.

An aerosol generation device comprising:

• a load configured 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
• circuitry configured to
• acquire a temperature of the load;
• execute feedback control based on the temperature of the load;
• and
• control the power that is supplied from the power source to the load, wherein
• the circuitry is configured to increase a gain in the feedback control or an upper limit value of the power that is supplied from the power source to the load so that the temperature of the load gradually approaches from a first temperature, at which a predetermined amount or more of aerosols is capable of being generated from the aerosol source or the aerosol-forming substrate included in the aerosol generation article and located in a position closest to the load, to a second temperature at which the predetermined amount or more of aerosols is capable of being generated from the aerosol source or the aerosol-forming substrate included in the aerosol generation article and located in a position most distant from the load.
