Abstract
PURPOSE:To obtain a stable controller for a motor driven looper without variation in the tension by feeding back the differentiated signal of the speed of a looper motor with the prescribed gain to a rolling mill speed control system, thereby enhancing the adaptability. CONSTITUTION:A current controller 8 controls a looper driving motor 6 in response to the deviation between the angular velocity N of a looper roller 4 via a multiplier 12 and a looper motor current reference Im. A speed controller 10 controls an input side rolling mill 1a driving motor 2 in response to the deviation between a signal responsive to the angle theta of the input side rolling mill speed reference signal V and roller 4 inputted from a loop amount controller 9, and the angular velocity N of the roller 4. In this manner, a stable motor driven looper controller which does not cause a variation in the tension can be obtained.
