The analysis of the control system developed for the DSP-15 arc steel-smelting furnace was carried out, its drawbacks were noted and promising solutions were identified for further improvement of this system. An approach is proposed to determine the optimality of the operating mode of the power circuit of an object, on the one hand, invariant to the size and shape of the input signals, which may not be differentiable, and on the other hand, it is relatively easy to implement. The possibility of representing the criterion for optimizing both in the phase-frequency domain (PFD) and in the time domain allows one to formalize the variation principle of reciprocity in these areas and consider the obtained values as clusters of system paradigms that complement each other well. When presenting signals in the PFD, this makes it possible to reduce the dimensionality of space and at the same time take into account the current changes occurring in it due to the introduction of a relative reference system. Such an approach to estimating the change in energy in the system is also convenient because, with optimal operation of the system, it is possible to combine the range of acceptable values and lead the process without approaching the optimal trajectory as in existing methods, but conduct it directly along this trajectory, which positively affects the efficiency energy conversion. The advantage of this method is to increase the speed of the control system and the possibility of more efficient control using the optimizer. Improving the efficiency of the optimizer contributes to the selection of low-frequency component, which characterizes the power, and allows better alignment of the effective performance ranges of the optimizer with the analyzed signals of the control system. To confirm and implement the marked advantages of the system it is planned to carry out tests in two stages.
