Abstract:
Rate of steel production in each country could lead us to rate of growth and development of that country. Having magnetite and hematite mines, inexpensive energy and labor, make steel production more feasible in Iran; so using technology to reach efficient production should be considered by clients.
Electrode regulation system controls the main input energy to electric arc furnace, i.e. electrical energy. Using this system could decrease tap to tap time and increase plant productivity. In present study, after brief review of literature, mathematical model for electrical and hydraulic model derived, and then different controllers designed for combination of these models. Results show good set point tracking and noise rejection for sliding mode controller
