Abstract

This paper presents an application of adaptive neuro-fuzzy networks which dynamically reconstructs the model of nonlinear v-i characteristic in electric arc furnaces. Electric arc furnaces represent complex, multi-variable processes with time-variant parameters, and their effective modeling is a challenging task. This paper shows that adaptive neuro-fuzzy networks lend themselves well to nonlinear black-box modeling of v-i behavior of electric arc furnaces. A successful implementation is described, and its performance is illustrated in comparison to measurements from an operational furnace.
