Aerosol generating device and method of controlling an aerosol generating device Technical Field The present disclosure relates to an aerosol-generating device and a method of controlling an aerosol-generating device, and more particularly to a method of updating an electrical power profile used to perform dielectric heating at an aerosol-generating device. Background Recently, there has been an increasing demand for alternative methods of overcoming the disadvantages of conventional cigarettes. For example, there is an increasing demand for systems for generating aerosols by heating aerosol-generating substances using aerosol-generating devices, rather than by burning cigarettes. Accordingly, studies on a heating type aerosol-generating device have been actively conducted. However, the heating type aerosol-generating device corresponds to a device using high power for a heating operation, and thus efficient use of the battery is required. In addition, accurate control of the heating temperature is required to provide a satisfactory smoking experience to the user. Therefore, for aerosol-generating devices, a solution for optimizing the power profile for controlling the heating is needed. Disclosure of Invention Technical problem The aerosol-generating device generates an aerosol by performing heating control according to a preset electrical power curve. However, due to factors such as the usage pattern of the aerosol-generating device, the surrounding environment, the performance of the heating control may be reduced by using only the preset power profile. Therefore, there is a need for a measure to improve the efficiency and performance of heating control by accurate electrical control of the aerosol-generating device.

According to another embodiment, a method of controlling an aerosol-generating device comprises the steps of setting a power curve to perform dielectric heating with microwaves on an aerosol-generating article in case a smoking phase is started, monitoring power feedback data for power supplied to a source generating a microwave signal while performing the dielectric heating with the set power curve during the execution of the smoking phase, determining if calibration of the power curve is required based on the monitored power feedback data in case the smoking phase is ended, and updating the power curve based on the monitored power feedback data in case the calibration of the power curve is determined to be required.
