Abstract: A method for controlling an aerosol generating device comprises receiving operating parameters of the aerosol generating device; determining an estimated temperature of a susceptor disposed within a consumable for the aerosol generating device based on the operating parameters; and controlling the power supplied to the inductor based on the estimated temperature of the susceptor. The operating parameters of the aerosol generating device comprise: ambient temperature; and an aspect of a power supplied to an inductor of the aerosol generating device. The estimated temperature of the susceptor is determined during an induction heating of the susceptor by the inductor.
