英文摘要：

According to the main circuit of the EAF, the electric state equation of electric arc furnace and the coupling characteristics among the three electrodes of electrode regulator system are analyzed.In this paper a PID neural network decoupling controller is designed for electrodes regulator system. How to initialize and update weights of neural network controller is also proposed. The simulation result shows that the decoupling performance, anti-disruptive ability and robust characteristics of controller are acceptable.
