Using the traditional power control algorithm based on the constant voltage driver metallurgy, vulnerable to external factors such as magnetic circuit saturation, hys原 teresis, cause unable to built accurate control model of defects, which reduces the power metallurgy control accuracy. Therefore, proposed a based on precise steppermotor control algorithm of metallurgy electricity control system. Using the method of multistage reactions can build stepper motor control mathematical model, calculation of metallurgy electricity controlrulesrelatedparameters, soastorealizepowermetallurgicalcontrol.Experimentalresults showthat this algorithm caneffectively improvethe accuracyofmetallurgy electricitycontrol, satisfactoryresultswere obtained.
