In the present embodiment, an aerosol generating device includes a load and a control unit. The load heats an aerosol-generating article containing an aerosol substrate holding or carrying at least one of an aerosol source and a flavor source, with the electric power supplied from a power source. The control unit controls the electric power supplied from the power source to the load. When the electric power is started to be supplied to the load in a non-operating state or when the load is in a preparatory state in which it is impossible to generate aerosol from the aerosol-generating article with a predetermined amount or more, the control unit controls the electric power supplied from the power source to the load with a feedforward control.在本實施形態中，霧氣產生裝置具備有負載及控制部。負載使用從電源供給來的電力，對包含有霧氣基材之霧氣產生物品進行加熱，該霧氣基材係保持或擔持有霧氣源及香味源的至少其中一者。控制部控制從電源供給至負載之電力。控制部在開始供給電力至非動作狀態的負載之情況、或負載處在不能使既定量以上的霧氣從霧氣產生物品產生的準備狀態之情況，採用前授控制來控制從電源供給至負載之電力。
