    • An improved plate flatness control method adapted to effect a control so that plate flatness of a rolled material is made optimum by adjusting manipulated variables. In determining correction quantities of the manipulated variables, under the constraint that upper and lower limits exist in at least one of the manipulated variables and the correction quantities, a weighted square sum of deviations of a plate flatness distribution in the width direction of the rolled material is taken as an objective function to determine, using a non-linear programming, correction quantities of the manipulated variables where the objective function becomes minimum, thus, to control the plate flatness of the rolled material on the basis of the determined correction quantities of the manipulated variables.
    • 改进的板平面度控制方法适用于通过调节操作变量使轧制材料的板平面度最佳化来实现控制。 在确定操作变量的校正量时,在至少一个操作变量和校正量中存在上限和下限的限制下,轧制材料的宽度方向上的平板度分布的偏差的加权平方和 被用作目标函数,以使用非线性规划来确定目标函数变为最小的操作变量的校正量,从而基于确定的修正量来控制轧制材料的板平面度 操纵变量。

    • One of the cartridge-type magnetic tapes set in a magazine is loaded into a magnetic tape unit, the magnetic tape thus loaded is data processed in the magnetic tape unit, and the data processed magnetic tape is then unloaded from the magnetic tape unit to be received into the magazine. This series of operations is sequentially repeated for all of the magnetic tapes set in the respective magazine steps. It is judged whether or not the data processed magnetic tapes set in the magazine have been replaced with fresh magnetic tapes yet to be data processed in the middle of the series of operations. If it is decided that the replacement of magnetic tapes has been done, the abovementioned series of operations, namely, the handling operations including the loading of a magnetic tape, data processing of the magnetic tape and receiving (unloading) of the magnetic tape, are continuously done for the magnetic tapes initially set in the magazine but yet to be data processed as well as the magnetic tapes replaced in the magazine and which are yet to be data processed.
    • 将设置在盒中的盒式磁带之一装载到磁带单元中,将如此装载的磁带在磁带单元中进行数据处理,然后将数据处理的磁带从磁带单元卸载为 收到杂志。 对于在相应的刀库步骤中设置的所有磁带,顺序重复该系列操作。 在该系列操作的中间判断是否已经将已经设置在该存储库中的数据处理的磁带替换为尚未被数据处理的新鲜磁带。 如果确定已经完成了磁带的更换,则上述一系列操作,即包括磁带的加载,磁带的数据处理和磁带的接收(卸载)的处理操作是 对于初期设置在杂志中但尚未进行数据处理的磁带以及在磁带中更换的磁带并且尚未进行数据处理的连续完成。
