Abstract
In a tandem rolling mill control system, an arithmetic operation on a looper torque command is adopted so that a signal obtained by integrating a looper angle deviation is not contained as a component, and a looper speed controller performs an arithmetic operation with a sampling period at a higher speed than a looper angle controller.
