摘　　要：电加热新型卷烟有降焦减害作用,其中加热温控系统为电加热新型卷烟烟具的核心。烟具主要存在起烟速度慢、发烟性能差等缺陷。采用阶跃响应法对烟具温度对象温度阶跃响应信号进行辨识,得烟具加热温度对象为一阶惯性纯滞后系统,并对烟具加热温度对象控制算法进行优化改进与仿真。仿真结果表明:改进的烟具温度对象加热延时时间缩短38.1%,温度上升时间缩短29.8%,调节时间缩短24.8%。研究可加快烟具起烟速度,提高发烟性能,降低系统的功耗,延长电池寿命,为烟具电路改进、开发提供理论指导。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 electricheating 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 electricheating cigarette heater circuit and the development of the electric-heating cigarette heater.
