摘　　要：针对导热油炉传统反馈PID算法温度控制存在的调节时间过长、超调量大、参数整定繁琐、干扰影响严重、闭环稳定性差的问题,基于“热量平衡法”的数学模型,利用前馈控制原理,将干扰量化,并通过前馈控制器限制PID控制器的输出幅值,降低超调量,减少调节时间。最终使温控系统的响应速度更快,稳定性更强。In response to the problems of long adjustment time,large overshoot,cumbersome parameter tuning,severe interference,and poor closed-loop stability in the traditional feedback PID algorithm temper-ature control of thermal oil furnaces,based on the mathematical model of"heat balance method",using the principle of feedforward control,the interference is quantified and through the feedforward controller the output amplitude of the PID controller is limited,the overshoot and the adjustment time are reduced.Ulti-mately,the temperature control system responds faster and has stronger stability.
