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

An aerosol provision device comprising:

• a housing;
• a consumable including aerosol-generating material, the aerosol provision device or the consumable further including an aerosol generator powered by a power source to generate an aerosol from the aerosol-generating material;
• 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, the signal being a modulated signal with an adjustable duty cycle, and the processing circuitry being configured to implement a proportional-integral-derivative (PID) algorithm to adjust the duty cycle based on the processing circuitry determining whether the measurements of temperature or the measurements of pressure take precedence for implementing the PID algorithm to adjust the duty cycle.
