Determination of membership function in the Fuzzy assay of caustic soda concentration

Caustic soda evaporation;  concentration;  Fuzzy detection;  Membership functions

When developing the caustic soda evaporation microcomputer control system, the membership function in caustic soda concentration fuzzy detection was discussed, and the data collected at the production site were analyzed and verified, and the fuzzy set of deviation, deviation change rate and output control amount involved in the fuzzy detection controller all conformed to the normal distribution. The practical application proves that the fuzzy detection controller of the membership function design has high accuracy for the measurement of caustic soda concentration, and the determination of the membership function provides a valuable reference for the development of microcomputer fuzzy control.
