Analysis of Interference in Gagemeter Conrol System on Rolling Mill with Simplified Model

Abstract

The Interference between operation-side and drive-side roll gap cotrol system arises in gagemeter control on rolling mill. It has become remarkable with high responsibility of roll gap control system. We have studied gagemeter control system with two asynchronous electrichydraulic servo systems, and found it is caused by the difffferences of their chacteristics, that is the diffrence of transfer functions between roll gap control systems in operation-side and drive-side.
