Abstract
A method of controlling a heater of an aerosol-generating device includes applying a first signal having a first frequency to a coil of the heater so that an alternating magnetic field is generated, determining a first value of an electrical characteristic of a susceptor indicated by the first signal, determining a first heating frequency based on the first value, and applying a first heating signal having the first heating frequency to the coil of the heater, so that proportional-integral-differential (PID) power control is performed based on a first power profile.

A method of controlling a heater of an aerosol-generating device, the method comprising:
- applying a first signal having a first frequency to a coil of the heater so that an alternating magnetic field is generated;
- determining a first value of an electrical characteristic of a susceptor indicated by the first signal;
- determining a first heating frequency based on the first value;
- and
- applying a first heating signal having the first heating frequency to the coil of the heater so that proportional-integral-differential (PID) power control is performed based on a first power profile.
An aerosol-generating device comprising:
- an induction coil configured to generate an alternating magnetic field;
- and
- a controller configured to control the aerosol-generating device,
- wherein the controller is further configured to:
- apply a first signal having a first frequency to a coil to a heater so that an alternating magnetic field is generated;
- determine a first value of an electrical characteristic of a susceptor indicated by the first signal;
- determine a first heating frequency based on the first value;
- and
- apply a first heating signal having the first heating frequency to the coil of the heater so that proportional-integral-differential (PID) power control is performed based on a first power profile.
