Intelligent decoupling for flatness and gauge control system in hot strip rolling

Hot strip rolling is a very complicated nonlinear process, and characterized by couple between automatic flatness control (AFC) and automatic gauge control (AGC). By analyzing actual rolling process and considering real application, a kind of intelligent decoupling algorithm based on single neuron PID is presented. The simulation results have shown this kind of controller has good performances of adaptively tracking target and resisting disturbances and superior to the conventional decoupled PID control in improving hot strip flatness and gauge accuracy.
