Application of fuzzy predictive control in adding medicament of water treatment

摘要

The adding medicament control of water treatment is an important step of the whole precess of generating power in a thermal power plant. In the light of the limitation of the conventional Smith predictive control, the fuzzy set theory is inroduced in this paper to keep the PH value of the circulating water in a predetermined range by regulating the amount of adding acid. In the end, an illustrative example of is presented to verify the effectiveness of the proposed intelligent control scheme.
