Burner-electrode position control of calcium carbide furnace based on BP-PID controller

This paper proposes a method of position control based on BP-PID controller to implement the electrode position control of calcium carbide furnace. Firstly, the characteristics of the arc of the burner-electrode are studied and the arc current under the maximum heating power is deduced theoretically. Secondly, the position control strategy of the electrode is determined. Finally, the BP-PID controller is implemented by using the S-function in Matlab and simulated in Matlab/Simulink. The simulation results show that this method can control the position of the burner-electrode of calcium carbide furnace.
