Abstract (en)
An aerosol generating device comprising a heater, a power source and memory comprising firmware.The power source is configured to supply power to the heater. The firmware is configured to control the application of power to the heater in a lower heater mode and a higher heater mode, wherein the lower heater mode has a lower mode temperature profile with a lower mode target temperature and the higher heater mode has a higher mode temperature profile with a higher mode target temperature.The firmware includes a control loop comprising a PID controller. The PID controller is configured to receive a temperature signal indicative of a measurement of the temperature of the heater, calculate, using the temperature signal, a PID controller output, and output the PID controller output. The control loop is configured to control, based on the PID controller output, a power applied to the heater from the power source to thereby regulate the temperature of the heater to a respective one of the lower mode or higher mode target temperatures.
