CLOSED-LOOP CONTROL OF TEMPERATURE AND PRESSURE SENSING FOR AN AEROSOL PROVISION DEVICE

Abstract: an aerosol provision device includes a housing; a consumable including aerosol-generating material. the aerosol provision device or the consumable includes an aerosol generator to generate an aerosol from the aerosol-generating material. the device includes a pressure sensor, a temperature sensor, and 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 is configured to output a modulated signal with an adjustable duty cycle to cause the high-side load switch to connect and disconnect power to the aerosol generator. the processing circuitry is 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.
