Application Studies of Fuzzy Control on Adding Medicament in Circulating Water Treatment

摘要

Considering the control problem of circulating water system in the power plants with pure delay, inertia, and sensitivity to the environmental temperature, this paper applies the fuzzy algorithm to adding medicament control in circulating water system. The main procedure of fuzzy control algorithm consists of fuzzification, fuzzy inference and defuzzification. The fuzzy input and output variables are chosen as seven classes. Then, according to the actual operation situations and the expert experiences, the fuzzy rules are determined in the form of table. The effectiveness of the proposed fuzzy control method is proved by some practical examples.
