Abstract
A method of operating a heat-not-burn, HNB, aerosol-generating apparatus is described. The HNB aerosol-generating apparatus comprises a heating element and a power supply for supplying power to the heating element. The method comprises: monitoring a temperature of the heating element during operation of the HNB aerosol-generating apparatus, wherein the monitoring comprises consecutively determining an instantaneous operational parameter value of the heating element to form a sequence of instantaneous operational parameters values of the heating element, wherein each instantaneous operational parameter value is indicative of an instantaneous temperature of the heating element; determining a rolling average value of the operational parameter of the heating element based on the sequence of instantaneous resistance values; determining a difference between one instantaneous operational parameter value of the sequence of instantaneous operational parameter values and the rolling average value; and if the determined difference exceeds a predetermined difference threshold, boosting a power output of the power supply from a default power level to a relatively higher boosted power level to supply the boosted power level to the heating element.
