摘要： PURPOSE:To accomplish the quick responsiveness and stability of tension control in a tandem rolling mill by synthesizing and outputting the output of a PI operation high in speed of response and the output of a PI operation low in speed of response in the rate of the 1st weight value to the 2nd weight value, in plural PI operations. CONSTITUTION:When the deviation of a tension from the target value is large, correction to the circumferential speed of a roll functions at high speed to make this deviation zero and tension control high in responsiveness is realized. On the contrary, when the deviation of the tension from the target value is small, correction to the circumferential speed of the roll to make this deviation zero functions slowly and tension control high and stable in accuracy is realized. Since the speed of response changes continuously in accordance with continuous decrease of deviation values, the tension control is not fluctuated by the change of the speed of response.
