| 摘 要： | 研究了母管制蒸汽锅炉控制系统大延迟、大滞后的工作特性。分析了一般模糊．PID控制器的控制特点，在此基础上给出了一种改进算法。通过在线调整参数。实现模糊．自调整比例常数PID控制。该算法比例常数随着偏差大小而变化，增强了控制性能，有效地解决了在小偏差范围内，一般的模糊．PID控制器无法实现的静态无偏差问题，提高了蒸汽温度控制系统的控制精度。系统采用集散控制系统（DCS）实现系统控制。在沈阳某电厂动力车间锅炉改造工程中的应用表明，锅炉蒸汽温度系统的控制品质得到了相当大的提高。

| Abstract: | The characteristics of steam boiler temperature control system with large delay and lag is studied. An improved method is presented based on analyzing the characteristics of current Fuzzy-PID control, The fuzzy-adaptive PID control is realized by adjusting the parameter online. The proportion parameters is changed according to the warp to enhance the control ability.This method solves the problem that in small warp area the genetic fuzzy-PID can not accomplish well, A DCS system is performed based on this method and proved to be quite efficacious. |
