    • Set values of a gauge-alteration-in-rolling amount after the next (i+1)-th stand and subsequent stands are modified, using the rolling results obtained when a leading end of a succeeding material passes through the i-th stand and the gauge results of the leading end portion of the succeeding material detected by the i-th stand outlet side gauge detector. The gauge results of the leading end of the succeeding material on the i-th stand outlet side is tracked up to the (i+1)-th stand, to thereby control the rolling speed of the i-th stand so as to make constant a mass-flow from the leading end of the succeeding material on the (i+1)-th stand inlet side. Thereby, the reverse off gauge caused at the succeeding stand, by turning on the AGC of the preceding stand, can be prevented and the gauge can be controlled to a desired value from the coil leading end portion.
    • 使用在后续材料的前端通过第i个支架时获得的滚动结果,在下一个(i + 1)支架和后续支架之后,设定换算量的值, 由第i台出口侧量规检测器检测到的后续材料的前端部分的规格结果。 跟踪第i台出口侧的后续材料的前端的测量结果直到第(i + 1)台,从而控制第i台的轧制速度,使其恒定 从第(i + 1)台入口侧的后续材料的前端的质量流。 因此,可以防止在后续的支架上引起的反向偏移量通过接通前一个支架的AGC,并且可以将线圈从线圈前端部分控制到期望的值。

    • A control system for controlling a plurality of control elements, which are effective to control of a given controlled system, is disclosed. In this control system, a characteristic value representing the characteristic of a given controlled system to be controlled is detected, and respective optimum manipulated variables of the plurality of control elements are derived on the basis of the detected characteristic value. The optimum manipulated variables are derived by setting a plurality of reference patterns representing different features of the characteristic value on the basis of a predicted value of the characteristic value, deriving degree of conviction that the detected characteristic value belongs to each of the reference patterns, presetting rules whereby a manipulated variable of each of the plurality of control elements is determined when the detected characteristic value belongs to each of the plurality of reference patterns, and deriving a manipulated variable of each control element on the basis of degree of conviction that the detected characteristic value belongs to each of the plurality of reference patterns and the manipulated variable determining rule preset with respect to each control element for each reference pattern.
