Simulink Study of the Dynamics of Electrical Mode Coordinates Combined Regulation of an Arc Furnace

A two-loop high-speed structure is proposed to regulate the electric mode (EM) of an arc steel melting furnace (AF) is proposed. A solution to improving the indices of the dynamics of EM coordinate regulation indices has been developed and studied. A comparative analysis of the dynamic indices of the proposed two-loop structure of fuzzy regulation of the coordinates of the EM arc furnace DSP-200 and the ARDM-T-12 serial arc power controller was performed. The time dependences of the main EM coordinates and the integral values of the quality indices of dynamics and energy efficiency during the regulation of random EM disturbances have been obtained on the computer model. The comparative analysis of the obtained dynamic indices has confirmed the effectiveness of the proposed high-speed two-circuit structure of the EM coordinate control system compared to the ARDM-T-12 controller.
