1. 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.
