This article is devoted to the development of the system of automatic control and to the adjustment of the size of the surface energy of polypropylene films in the flexographic solvent printing inks. According to the accepted term a membership function and fuzzy knowledge base of the printing speed impact and the surface energy of the film on a needed dose of corona discharge are formed. Basing on the algorithm of Mamdani with the help of the defuzzification method «the center of gravity», the calculations have been conducted using MATLAB FIS-editor. А model of the automatic system of the determining of the corona dose and the calculation of the corresponding power generator of the corona station have been built.

Keywords: surface energy, polymer films, membership function, knowledge base, fuzzy logic.
