Modelling and Control of an Electric Arc Furnace

Authors

Abstract

In an Electric Arc Furnace (EAF), electrical energy is the main source of power used when melting scrap. In order to optimize the power consumption, the EAF must be properly understood. Also, since the main source of power are the electric arcs, its electrical and thermal properties must be analyzed. The arc power depends on its length and it is adjusted by moving the electrodes. In order to maintain the desired power levels, efficient control of the electrode movements is required.
This thesis presents an object-oriented model of the EAF where its main subsystems, namely the electrical system, the electrode positioning dynamics and the disturbances are analyzed separately. Furthermore, a fuzzy P-like impedance controller, based on the model implemented, is also presented.
