摘　　要：论述了基于工业PC机（IPC）的一种高精度温度控制系统的设计。针对一类工业电阻炉的特性和主要扰动产生的原因，给出了一种反馈加前馈的复合PID控制算法，得到了反应迅速、低超调、低温段为（500±0．75）℃和高温段为（1000±0．5）℃的高精度控制特性。This paper deals with the design of high precision temperature controlling systembased on Inductrial Persional Computer (IPC). Also, the controlling in algorithm of feedbackPID adjusting with feedforward compensator is given in accordance with the characteristics of atype of industrial resistance furnance and the reasons to cause main distrubances. The highprecision controlling features of quick reponses, low overshoot δ and low precision of(500± 0. 75) ℃ and high precision (1000 ±o. 5) ℃ are obtained.
