METHOD FOR CONTROLLING VIBRATION OF SHAFT AT ROLLING ROLL

摘要

PURPOSE: A control method for suppressing the vibration of a shaft at a rolling roll is provided which improves load response characteristics by compensating the vibration of the shaft during acceleration and deceleration as maintaining characteristics of an existing proportional integration controller. CONSTITUTION: In a vibration control method of a roll shaft in which a vibration of a shaft connecting a motor with a revolution body is controlled through proportional integration control, the method for controlling the vibration of a shaft at a rolling roll comprises the steps of outputting a control torque(Te) according to a standard speed inputted into a speed controller(41); and controlling a motor speed by controlling the control torque(Te) inputted by an observation device(43) with a feedback gain.
