Application of Disturbance Rejecting Fuzzy Controller in Electric Arc Furnace


Article Preview

In this paper, the design of a disturbance rejecting fuzzy controller (DRFC) is applied to the electric arc furnace electrode regulation system. In order to improve traditional PID which is slow response and vulnerable to disturbance, we introduce two model reference fuzzy adaptive control mechanism, one of which is designed to improve response speed and reduce the sine disturbance of the length of arc, and the other of which is designed to reduce the current coupling random disturbance. Simulation results showed that by using a DRFC can acquire better dynamic characteristics in the electric arc furnace electrode regulation system, and has stronger suppression capacity.
