The invention provides an
automatic control method used for a submerged arc furnace
electrode and based on high-precision fuzzy control. According to
electrode current deviation ei, a change rate
delta ei of the
electrode current deviation, the depth dt of the electrode inserted into burden and a change rate
delta dt of the depth of the electrode inserted into the burden, a high-precision fuzzy controller is adopted to adjust the variation mt of the position of the submerged arc furnace electrode, wherein a
membership function and a fuzzy control rule of the fuzzy controller are obtained through expertise, and output of the controller is obtained through fuzzy neighbor distance weighted interpolation calculation, so that the control accuracy of the fuzzy controller is improved. The
automatic control method used for the submerged arc furnace electrode and based on high-precision fuzzy control provides guarantee for safe and reliable operation of the submerged arc furnace which can operate in a stable manner, so that labor intensity of a worker can be reduced effectively, the maintenance quantity is reduced, the work environment is improved, and better conditions are provided for following
harmonic suppression.
