Управление концентрацией травильного раствора непрерывного травильного агрегата с использованием нечетких LR-интервалов

Abstract

The method of uncertain estimation for oxide film thickness on continuous carbon steel strip is pickling proposed with use of color identification of this film. Each color corresponds to appropriate uncertain LR-interval of film thickness. The logic rule of sulfuric acid concentration controlling is considered. The problem is interpretated as necessary resupply problem for pickling liquor to the level defined by function that is forming on the base of LR-interval treatment
