Abstract
The hierarchical structure of the adaptive optimal control system for electric mode (EM) of the electric arc furnace is proposed. Components of the systemic control vector and a technique of its synthesis for complex criterion of minimum dispersion and maximum arc power is substantiated. The model of adapting the control vector to change of technological stages and stochastic characteristics of perturbations was developed. Systemic solutions for recognition of technological stages of steel melting and identification of moments of their change based on a neural network were studied. Circuit design solutions for operational measurement of informative parameters of the steel-melting process using wavelet transform are proposed. Results of the experimental study of the neural network melting stage recognition system for electric arc furnace DSP-3 are presented.
