Closed-loop control of temperature and pressure sensing for an aerosol provision device

An aerosol provision device comprising:

• a housing;
• circuitry;
• and
• one or more of a coupler or a receptacle structured to engage and hold a consumable including aerosol-generating material, the aerosol provision device or the consumable further including an aerosol generator powered by a power source under control of the circuitry to energize the aerosol-generating material to generate an aerosol for delivery to a user,
• wherein the circuitry includes:
• a pressure sensor configured to produce measurements of pressure caused by airflow through the housing;
• a temperature sensor configured to produce measurements of temperature of one or both of the aerosol generator or the aerosol-generating material;
• a high-side load switch coupled to or coupleable with the aerosol generator;
• and
• processing circuitry coupled to the high-side load switch, the pressure sensor, and the temperature sensor, the processing circuitry configured to output a signal to cause the 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 is a modulated signal with a duty cycle that is adjustable, and the processing circuitry is configured to implement 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.
