摘要 |
<p>To prevent inadmissible electrode oscillations in a regulating circuit for regulating the impedance of an arc furnace (1) comprising at least one electrode (2), an hydraulic lifting drive (5) for the electrode (2) and a controller (10) controlling the lifting drive (5), the input of which controller is associated with an actual-value transmitter (13) for the impedance and an input (15) for the impedance set point, a correction stage (16) for the controller gain is proposed which can be operated via a transmitter (17) for the control system gain in a sense of a change in the controller gain which is opposite to the change in the system gain.</p> |
