Abstract: The present disclosure relates to electronic cigarettes, and in particular to a control method of an electronic cigarette and an electronic cigarette. The method includes: activating an electromagnetic heating component to output a predetermined output power at a first stage, so that a heating device heats up; feedback controlling the output power of the electromagnetic heating component through a first PID algorithm according to the temperature information of the heating device and a 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. The control method of the electronic cigarette provided in the embodiment adopts a combination of PID algorithms and electromagnetic heating.
