Abstract：The control effect of three-phase electrode is severely affected by the coupling between three electrode of electric arc furnace, and the large maladjustment is easy to occur in ordinary single-phase control method without considering the coupling. On the basis of analyzing the three- phase electrode coupled, a decoupling method on current compensation is derived in this paper. The method has theoretical significance for electrode decoupling, but the compensation coefficient is associated with the arc length on time and the computational complexity is very great. Therefore, a fuzzy controller of single-input and double-output, which is used to compensate and decouple, is introduced based on decoupling method of the current compensation. Simulation is made on decoupling performance and noise immunity of the controller by Matlab/Simulink and the comparison has been made before and after decoupling by the collected data on field. The results show that the fuzzy decoupling controller can eliminate the strong coupling effect between the three-phase electrodes, and improve the efficiency and reduce energy consumption of electric arc furnace steelmaking.
