Research on Predictive Functional Control in Flatness Feedback Control System of Hot Tandem Rolling
Currently in the flatness feedback control of hot strip mill it mainly adopts conventional PID controller, the parameters of which are often designed to a kind of situation and are invariable, so it is difficult to keep flatness well in hot tandem rolling. On the base of analyzing the shape generation theory and model prediction control theory, the flatness control system by adjusting last stand bending force is designed using predictive functional control. The predictive functional control with small on-line computation can arrive to enhance the precision of the flatness control. The simulation results of the flatness control system indicate that the systems dynamic response performance is advanced observably, and it also has more favorable characteristics than using conventional PID controller.
