Abstract
The article describes the improved system for control the hydraulic drive of the EAF-250 electrodes motion (OJSC «MMK Metalurji», Iskenderun, Turkey). The analysis of the disadvantages of existing control system HIREG (Danieli, Italy), which is installed on the EAF-250, was reviewed. The structure of improved proportional admittance control, which implementation will allow to simplify the setup process, to reduce the number of unique characteristics of the control, and also to improve the dynamic characteristics of the system work quality was provided.
Keywords
