Real-time tension control in a multi-stand rolling system

摘要: The problem of real-time tension control in a metal-strip processing line is addressed. metal strip changes due to not only the speed difference but also thickness at ends span. mathematical dynamic model which describes relationship between change and roll-speed improved include effect on variation. Through computer simulation this model. parameter sensitivity analysis static characteristic study are carried out. variation turned out be very sensitive as well strip. In rolling process, master drive usually located last stand. speeds rollers upstream stands adjusted with respect stand compensate for regulation. A new strategy multi-stand process suggested. transfer phenomena used design suggested controller. developed controller system. set requirements Based requirements, software system designed was by using Vx Works scheduler Force Target board. cancellation mechanism roll gap interaction clearly defined derived study. It confirmed that needs less efforts shows better performance than those existing method process.
