<p>PURPOSE:To improve the accuracy of plate thickness by learning the plate thickness measured value of the preceding path as the composite error of mill and reflecting it to the next path about the load depending term between the controlling errors of the plate thickness of GM model and the actual measured value. CONSTITUTION:On the time of the plate thickness controlling for the thick plate rolling based on GM model, the controlling error of the plate thickness obtained from GM model and the actually measured plate thickness is separated into the load depending term and the other's and is treated. On the treatment of the load depending term, by learning the actually measured thickness of the preceding path with GM model and reflecting the rolled stock are corrected. Therefore, the accuracy of plate thickness is improved.</p> |
