Abstract
An embodiment of the present invention discloses an aerosol-generating device, the device including a heater for heating an aerosol-generating substrate, and a controller for controlling power supplied to the heater through a proportional integral differential (PID) method, based on an integral control weight determined according to an initial temperature of the heater.
Claims19
An aerosol-generating device comprising:
- a heater configured to heat an aerosol-generating substrate;
- and
- a controller configured to:
- control a first smoking section and a second smoking section consecutive to the first smoking section,
- determine a temperature after smoking ends in the first smoking section as an initial temperature of the heater, and
- control power supplied to the heater in the second smoking section through a proportional integral differential (MD) method, based on an integral control weight determined according to the initial temperature of the heater.

A method of controlling power supplied to a heater of an aerosol-generating device in a first smoking section and a second smoking section, the method comprising:
- determining a temperature after smoking ends in the first smoking section as an initial temperature of a heater of an aerosol-generating device;
- determining an integral control weight for integral control in proportional integral differential control based on the determined initial temperature of the heater;
- and
- maintaining a temperature of the heater in the second smoking section consecutive to the first smoking section based on the determined integral control weight after the temperature of the heater reaches a preheating temperature.
