Fuzzy extreme control and electric mode coordinates stabilization of arc steel-melting furnace

The structure of a multiloop system of fuzzy extreme control of modes and optimal stabilization of electric arc furnace coordinates using fuzzy inference systems has been substantiated. A method for calculating integral values of energy efficiency indices is proposed, using which performance curves of electric arc furnace were built. Their analysis showed that fuzzy models of optimal control and control of electric mode coordinates enables comprehensive improvement of indices of electric and technological efficiency of electric arc furnaces and electric power quality.
