PROBLEM TO BE SOLVED: To suppress the degradation of convergence properties for a search of an optimum value of an evaluation function J(w) accompanying the occurrence of a sliding mode in a case of expressing a model for calculating a future predicted value z^ of a specific state quantity z by a PWARX model.SOLUTION: In a calculation of any one of a predicted value z^(w+Δ) and z^(w-Δ), the occurrence of a sliding mode is predicted. When the occurrence of the sliding mode is predicted, a small perturbation Δ is re-set to a smaller search value by a binary search method-based calculation. Setting to the new small perturbation Δ causes a future prediction for a neighborhood value w-Δ to transition between a segment region Xand a segment region X, so that the sliding mode can be avoided.SELECTED DRAWING: Figure 8 |
