Abstract
An instantaneous value of a learning coefficient is calculated based on a gap between a result value and a result recalculation value, and an update value of the learning coefficient is calculated from the instantaneous value. The calculated update value is recorded in a cell corresponding to present rolling conditions. A predetermined number of neighboring cells having small spatial distances from a target cell corresponding to next rolling conditions in a space having rolling conditions as coordinate axes are selected from cells in which respective evaluation results of recency, saturation, and stability of the learning coefficient satisfy criteria. An estimation value of the learning coefficient in the target cell is then calculated by polynomial interpolation. The most recent update value of the learning coefficient is then corrected with the estimation value, and used as a use value of the learning coefficient in the next rolling conditions.
