オブザーバによる2スタンドスキンパスミルの振動抑制制御

抄録

Skin pass mill is the equipment for the thermal-refing metal rolling of stainless plants, etc. Usually, rolling mill is elastically coupled with the motor driving a rolling mill. Shaft torsional vibration is often generated, when we attempt to get the high control performance of the rolling mill. Such a vibration causes degradation of product quality. In this paper, we propose a method of suppressing the vibrations of steel plate tension using Observer. This method has the excellent characteristic that the vibration-suppressive system is easily constructed just by adding the observer to the conventional control system. This is detailed hereunder.
