摘　　要：熔融拉锥法是制作熔锥型光纤器件的基本工艺[1],常采用火焰加热。由于火焰形成的温度场不稳定,严重影响了耦合器等光纤器件性能的一致性[2]。设计了一种以电阻加热器为发热元件的PID温控系统,建立了其数学模型,运用MATLAB计算出控制参数,采用所得PID控制参数,经过在线调试,获得了良好的控制效果。Fused biconical taper is a basic production technology of fused taper optic devices. Flame heating is usually selected. Because of the instability of flame temperature field,the conformity of the optic devices is not good. A PID temperature control system is designed,using the microresistance heater as heating element. By building mathematic model,the MATLAB tool is applied to calculate the controlling parameter of PID . Based on the parameter,the temperature control equipments is finished in good working order.
