Abstract: A method of controlling heating in an aerosol-generating system including a heater is provided, the method including: providing a predetermined power to the heater and monitoring a resistance of the heater, the monitored resistance being indicative of a temperature of the heater; monitoring for a predetermined condition and upon detection of the predetermined condition, recording the resistance of the heater; determining a target resistance corresponding to a target temperature of the heater based on the recorded resistance; and detecting a dry puff when the recorded resistance increases above a threshold value or when a power required to maintain the heater at the target resistance decreases below a threshold value. An aerosol-generating system including a heater, a power supply, and a controller to perform the method, is also provided.

Abstract: A method of controlling heating in an aerosol-generating system including a heater is provided, the method including: a first control step in which a predetermined power is provided to the heater and a resistance of the heater is determined, the determined resistance being indicative of a temperature of the heater; monitoring for a predetermined condition, and upon detection of the predetermined condition, recording a resistance of the heater; determining a target resistance corresponding to a target temperature of the heater based on the recorded resistance; and a second control step in which the predetermined power provided to the heater is controllably adapted to drive the resistance of the heater towards the target resistance such that the heater is driven towards the target temperature corresponding to the target resistance. An aerosol-generating system and a controller for an aerosol-generating system are also provided.

Abstract: A method of controlling aerosol production in an aerosol-generating system is provided, the system including: data storage, an aerosol-generating element, a flow channel configured to provide an air flow past the element when a user puffs on the system, and a flow sensor configured to detect the air flow; and the method including: increasing a power supplied to the element from a first power to at least a second power when the flow sensor detects that a flow rate of the air flow is greater than a first threshold, storing measurements taken by the flow sensor in the data storage, using measurements stored in the data storage to intermittently calculate an estimate of a remaining volume of the puff, and decreasing the power supplied to a third power when the estimate of the remaining volume is less than a second threshold being or indicative of a measure of volume.
