Patent attributes
An aerosol generation device includes: a load configured to heat an aerosol generation article including an aerosol-forming substrate configured to hold or carry at least one of an aerosol source and a flavor source; and a controller configured to control power that is supplied from a power source to the load. When a 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, the controller is configured to acquire the temperature of the load and a degree of progress of the phase, to execute feedback control so that the temperature of the load converges to a predetermined temperature, and to increase a gain in the feedback control or an upper limit value of the power, as the degree of progress progresses, in the feedback control.
