Intelligent Controlling System Of Arc Furnace Based On ANN

An automatically controlling system of arc furnace has used two industrial computers in this paper, based on the fact and requires of customs. One computer achieves electrode lifter controlling as basal automatic control, with expert system and neural network predicting model; the other computer shows trends and data as processing workstation, analyzing, calculating and optimizing technical parameters from basal control.Owing to the delay in change of regulation of executing agency with respect to changes in realistic state, arc furnace is predicted the state in the next time, with NN predicting model, so that the current wins comparative stabilization and impact of trashy power is reduced. This is a way of winning much output with little input, that can change intelligentized intrinsic system and reduce charge. This system sends data gathering from scene to PLC to regulate and analyze, and achieves optimization parameters to send to PLC to control, in virtual of the powerful capacity of analyzing and calculating. Then the data are sent to data-base to manage. The host is charged with managing, analyzing, calculating, counting, report-printing, menu-displaying and communicating. The system uses the popular double-deck controlling, namely the host communicates online with PLC, at the same time it communicates with other stations by TCP/IP protocol.The electrodes regulate timely, quickly and true, with controlling three-phase voltage and current, so that power is stable comparatively. The host correct and intervene timely the basal control parameters and reach the result of flexible controlling.
