Abstract: An aerosol-generating device is provided, including: a heating element configured to heat an aerosol-forming substrate to generate an aerosol; a temperature sensor configured to measure a temperature of the heating element; an aerosol-monitor for measuring an aerosol property including at least one of a physical property and a chemical composition of a generated aerosol, the aerosol-monitor being disposed at or along a flow channel downstream of the heating element; a controller configured to adjust a power supplied to the heating element based on: i) a measured heating element temperature in a first feedback control loop, and ii) a measured aerosol property in a second feedback control loop; and an auxiliary aerosol controller for adjusting aerosol properties of the generated aerosol, the controller is further configured to adjust at least one control variable for the auxiliary aerosol controlling means based on the measured aerosol property in the second feedback control loop.
