Simulation on adaptive control of electrode regulator systems of arc furnace

The authors present research on the adaptive control of electrode regulator systems of arc furnaces. First, a model of an electrode regulator system is obtained, and then a series of linear transfer functions of the systems are used equivalently instead of the nonlinear transfer operator. Based on this, a plan of model reference adaptive control is put forward. The results of simulation shows that adaptive control systems have better dynamic characteristics than PID control systems, and greatly strengthens the capability of restraining disturbances of arc length.
