Abstract

An adaptive fuzzy robust controller is designed to improve the electrode control of three-phase electric arc furnace electrode regulator system. The design process of robust fuzzy control system is proposed in detail. The impacts of tracking error and approximation error to parameter adaptive law are considered. The approximate error and external disturbances compensate controls are adopted. The simulation results show that this control algorithm has good dynamic response and stable-control accuracy, has a strong robustness for external disturbances and structural parameter uncertainty.
