Application of Real?Time Generalized Predictive Controller to Tension Control Systems of Tandem Cold?Rolling Mill

For the real time restriction of generalized predictive control in tandem cold?mill tension control systems,a set of directive solution formulae of Diophantine equation and proof are presented,which avoids recursive computation on line and decreases the burden of the generalized predictive controller in computation.It is also in favor of its application to fast systems.The simulation shows that our method can save running time online sharply.So the applied potentiality of generalized predictive control is exhibited.
