1. A control method of an electronic cigarette, which is used for controlling an electromagnetic heating component to heat a smoking article to produce an aerosol, the electromagnetic heating component at least comprising an induction coil and a heating device, the control method comprising:
determining a preheating temperature, the preheating temperature being greater than a critical temperature at which a tobacco material in the smoking article is heated to aerosolize;
activating the electromagnetic heating component to output a predetermined output power at a first stage, so that the heating device heats up;
receiving temperature information of the heating device collected in real time by a temperature sensor, feedback controlling the output power of the electromagnetic heating component through a first PID algorithm according to the temperature information and the preset preheating temperature, so that the heating device reaches the preheating temperature; and
after the heating device reaches the preheating temperature, adjusting the output power of the electromagnetic heating component at a second stage, so that the heating device keeps a target smoking temperature, the target smoking temperature being less than the preheating temperature.
