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.
