Development of PI-controller optimal tuning method

Aim. The research aims to develop a method of optimal PI-controller tuning, which allows to take into account the constraints and to minimize the undesirable indicators of the automatic control quality. Method. In order to carry out the investigation, the problem of optimal PI-controller tuning was stated in a general form. The analysis of the elements of the problem has been conducted. It allowed substituting the elements to the requirements of individual minimization criteria.

Reduction of phase interactions in control processes of “arc steel-making furnace – power supply system” complex electrical technological system

The article offers system engineering solutions for enhancing the single-phase autonomy of the processes of controlling the coordinates of electrical mode (EM) in an electrical mechanical sub-system of moving the electrodes of  an electric arc steel-making furnace by including a cross-link compensator into its structure.
