Unclear Power Regulation System for Vacuum Arc Furnace

Abstract

In this paper, we review the task of improving the dynamic characteristics of vacuum arc furnace power controller. The paper proposes solution of this task by the use of fuzzy logic controller based on Sugeno algorithm within a speed loop of electrode positioning drive. It also proposes the application of compensation method for dead zone along the arc length using fuzzy logic device also based on Sugeno algorithm. The results of studying the dynamic characteristics of vacuum arc furnace power control system with classical and fuzzy controllers are shown.
