摘　　要：保定热电厂450t/h CFB锅炉的原床温控制系统采用的是常规PID控制,针对原系统响应慢、执行机构动作频繁、磨损较大的问题,本文提出采用模糊控制代替原有的常规PID控制,对改造前后系统的运行效果进行比较,结果表明,改造后能够有效地改善系统的动态品质,提高抗干扰能力,对工况改变时模型变化的鲁捧性有较大提高,此项改造为CFB锅炉的稳定运行提供参考。The bed temperature＇s primary control system of 450t/h CFB boiler in Baoding Cogeneration Power Plant is regulatory PID control, to solve the problem of slowly responding, frequently operation of actuator, biggish abrasion, this paper proposed that primary regulatory PID control is replaced by fuzzy control. Operation results of system before and after the reconstruction are compared, the results show that the reconstruction is effective, this reconstructi on experience makes great reference for ensuring the stable running of CFB boiler.
