Jun 01, 2007 Abstract In the rolling mill main drive system, a shaft torsional vibration is often generated when a motor and a roll are connected with a flexible shaft. The state feedback control can effective suppress the torsional vibration of the main drive system of rolling mill. Because of the difficulty of measuring the load speed and the shaft torque, over the sensitive of Luenberger observer.
