Pole Assignment Self Tuning Control and Its Application in Gauge Control System for Cold Strip Mill
极点配置自校正控制及其在冷带轧机厚控系统中的应用

In view of the parameters time varying of the controlled plant of gauge control system for the cold strip mill in the rolling process,especially in different paths rolling, a kind of self tuning controller is designed by using the internal model principle to add the integrate factor to the conventional pole assignment self tuning controller. Thus it can effectively eliminate the steady error of gauge control system.The experimental result shows that the designed self tuning controller can ensure the accuracy of gauge control system, the quality of products has been improved evidently.
