The solution of the actual problem of energy saving when using electric arc process aggregates of industrial production due to the effective dynamic extreme control of energy consumption under the conditions of real intensive action of random noise and technological disturbances has been considered. The increased noise immunity of the considered method of energy-saving dynamic extreme energy management of electric arc aggregates is ensured by using as a testing disturbing effect on the energy consumption process in the form of the orthogonal Walsh function, the unique properties of which allow to effectively solve the problem and to use the extreme method of generating a control action using the principle of the fuzzy logic and fuzzy sets.  The current value of the change in the electric power supplied to the process electric arc aggregate is determined by the magnitude and sign of the integral evaluation of the energy consumption process response to the input effect as a result of changing the electrode position at a constant predetermined position of a voltage switch of a furnace transformer.
