Abstract: A12(so4)3 dosing is an unlinerjong lag control system in water treatment. It is difficult to set up mathematic model. This paper introduces a new A12(so4)3 dosing system based on fuzzy PID controller and gives detailed design process. The result indicates that this fuzzy PID used in this structure can achieve better result than normal digital PID controller used in the structure of typical A12(so4)3 dosing system.

摘要： 水处理过程中对源水加矾是一个非线性、大滞后的控制,而且难以建立数学模型,该文阐述了用参数模糊PID控制实现自动加矾, 并给出了具体设计过程,在实际运行中取得了良好的效果。
