Abstract

The purpose of the study is to ensure the functioning of the electric arc technological units, such as an electric arc furnace and a ladle furnace in a power saving mode. The authors propose an energy-saving noise-immune method of search the intelligent optimal control of the electrical mode for arc technological units. The method is characterized by division in time of searching testing interaction to a process with the subsequent formation of a working control accord-ing to the integral evaluation of the response of the optimized process to the testing action. For the construction of a new automatic control method, the authors review: the structure of control loops for electric arc technological units, the functioning of the method for controlling energy regimes, and the results of method modeling on the example of electric arc furnace. The noise immunity of the method is provided by forming a plan of testing actions in accordance with the unique properties of the orthogonal Walsh function. Using the energy-saving systems for automatic control of energy modes of arc technological units makes it possible to ensure the maximum hourly capacity of the unit by determining and maintaining the maximum electric power allocated in the arc and to ensure the minimum consumption of electric energy with the minimum cost of finished products, which are obtained using electric arc process units.
