Analysis on the Temperature Object of Electric-heating Cigarette Heater

Electric-heating cigarette heater has the function of reducing the tar and other harmful components.The heating temperature control system is the core of electric-heating cigarette heater.It mainly exists slow smoking speed,poor smoking performance and other defects of electric-heating cigarette heater.The step response signal of the heating temperature object was identified by using the step response method.It obtained that the heating temperature object is the first-order inertia pure delay system.And the control algorithm of the heating temperature object was optimized and simulated.The simulation results identified that the delay time of heating of the optimized heating temperature object was reduced by 38.1%,the temperature rise time was reduced by 29.8% and the adjustment time was shortened by 24.8%,which improves the smoke speed and performance;reduces system power consumption and extends battery service life,provides theoretical guidance for the improvement of electric-heating cigarette heater circuit and the development of the electric-heating cigarette heater.
