Owing to that the EAF electrode regulator system has nonlinear, delay, random characters; the sliding mode control with good robustness was combined with the fuzzy control which is not entirely depend on the model. A fuzzy sliding mode control (FSMC) strategy was proposed and applied to electrode regulator system. This paper presents the simulations of periodic arc length disturbance and random arc length disturbance. Simulation results show that the fuzzy sliding mode control not only can reduce the system error that caused by the uncertainty of the system, but also enhance the system against internal disturbances and external disturbances. Furthermore, it can effectively solve the system chattering problem.
