FIELD: rolled stock production. SUBSTANCE: automatic control system provides rational distribution of processes for controlling strip thickness difference in mill stands without overshooting and excessive fluctuations due to using one extremely quick-action regulator acting upon reduction value of strip in last stand. Previous stands work in coincidence with the last one by decreasing value of strip thickness difference until static error value and transmitting it for canceling to next stands. Previous stands operate in such a way that to maintain process for controlling strip thickness difference in last stand also against strip motion direction. System operates at any reduction values in last stand. EFFECT: optimal strip thickness control with use of all stands of rolling mill. 2 cl, 2 dwg
