<p>PURPOSE:To highly precisely predict a physical phenomenon in the work of the next material by performing updating separately for a learning coefficient for respective layers corresponding to the respective layers and a time sequential learning coefficient in common to the respective layers at the time of correcting a control model. CONSTITUTION:In the case of updating the learning coefficient, a control result and a control target value are compared (step ST12) and when the difference is within a predetermined threshold value, the learning coefficient is not update. When the difference exceeds the threshold value, the learning coefficient CSo(i) for the respective layers is read from the instantaneous value C of the learning coefficient, and a table and the instantaneous value CT of the times sequential learning coefficient is calculate (ST13). Then, the time sequential learning coefficient CTo before the updating is read from the table and the new time sequential learning coefficient CTn is calculated (ST14). Then, by using the learning coefficient CTn, the instantaneous value CS(i) of the learning coefficient for the respective layers is calculated (ST15). Then, from the learning coefficient CSo(i) before the updating and the instantaneous value CS(i), the new learning coefficient CS(i) for the respective layers is calculate (ST16).</p> |
