摘　　要：针对PID在水泥生产线冷却过程中实际应用所发现的问题,提出了将Fuzzy-PID复合控制算法应用于现场的控制思路,该算法将Fuzzy和PID两种控制方式的控制优点有机结合,根据多次现场实验得到的模糊切换隶属度函数在两种控制方式下自动切换,该控制既能在动态过程中快速调节,又能在稳态过程中准确调节。冷却过程控制软件采用VC++编写,通过在某水泥厂的实际应用表明了该方案的正确性和实用性。To the problems of PID control algorithm applied to the cooling process in cement production line, a composite fuzzy-PlD control in cooling process is proposed. The advantages of fuzzy and PID control algorithm are combined in the proposed controllen. Fuzzy membership functions based on the field experience can switch automatically in this hybrid control way. The method can not only adjust fast in the dynamic process, but also adjust accurately in the steady state process. The software is compiled by VC ＋＋. The application in some cement plant show the correctness and practicability of this method.
