Claim 8:
9. A method of operating an aerosol provision system equipped with circuitry including processing circuitry, and an aerosol generator powered by a power source under control of the circuitry to energize aerosol-generating material to generate an aerosol for delivery to a user, the method comprising:
producing measurements of pressure caused by airflow through the aerosol provision device;
producing measurements of temperature of one or both of the aerosol generator or the aerosol-generating material; and
outputting a signal by the processing circuitry to cause a high-side load switch to switchably connect and disconnect power from the power source to the aerosol generator, based on the measurements of pressure and the measurements of temperature,
wherein the signal output by the processing circuitry is a modulated signal with a duty cycle that is adjustable, the processing circuitry implementing a proportional-integral-derivative (PID) algorithm to adjust the duty cycle based on the measurements of pressure and the measurements of temperature according to a predetermined relationship between pressure and temperature, and
wherein the processing circuitry determines from the predetermined relationship whether the measurements of temperature or the measurements of pressure take precedence for implementing the PID algorithm to adjust the duty cycle.
