Rolling technique process needs powerful technical support and control level of rolling has been turning point at present. The key to some questions has not been solved thoroughly by the limitation based on conventionalcontrol theory. It is very necessary to realize forward development in control performance by introducing new control theory and method. It is always primary object to improve gauge control accuracy in hot strip mills. Limitation based on conventional PID is emerged when the controlled system is complex, nonlinear and time-variety. A new control strategy based on RBF-PID is introduced and has been applied in high nonlinear, time - varying hydraulic MN- AGC of 1700ASP The practical results have shown that the controller can improve the precision of the product gauge and has good performance.
