Research on Fuzzy-PID control strategy for AC arc furnace electrode regulator system

This paper studied the Fuzzy-PID control strategy for AC arc furnace electrode regulator system. Based on the classical PID control, this paper used the basic theories and methods of Fuzzy Mathematics to adjust the PID parameters, realized the Fuzzy-PID control strategy, applied it in electrode regulator system and then made the simulation. The simulation results showed that the control strategy of the electrode regulator discussed in this paper adjusted the position of the electrode accurately, regulated the arc length of the electrode to an expectable value. Therefore, this discussed control strategy could suppress the power grid fluctuations, reduce power consumption and save energy.
