摘    要：针对某电解铝厂烟气净化系统的排烟风门开度控制中存在的非线性、时变及难以建立精确的数学模型等问题进行了研究,提出了一种基于模糊控制算法的风门开度控制系统,通过建立PLC模糊控制表设计模糊控制算法,并采用PLC接口模块进行模糊控制。将该模糊控制算法应用到该电解铝厂的排烟风门开度控制中,取得了很好的控制效果。

Abstract: In air damper opening control of gas cleaning system at a certain electrolytic aluminium plant,there are non-linearity,time-varying and difficulty to build accurate mathematic model.An air damper opening control system based on fuzzy control algorithm was put forward.Fuzzy control algorithm was designed through building PLC fuzzy control scheduling,and fuzzy control was applied via PLC interface module.The fuzzy control algorithm has been applied to air damper opening control in electrolytic aluminium plant and good control effect was achieved.
