Summary: | To provide a design method that can determine an optimum structure of an FB controller imparting the best evaluation value by making a search at a low frequency, and thus make FB controller design efficient.SOLUTION: A design method comprises: a selection step (Step1) of applying optimization algorithm to select a structure candidate for a feedback controller; a parameter design step (Step2) of performing parameter designing for each of selected structure candidates; an evaluation value order step (Step3) of using evaluation values for a design parameter to rank the selected structure candidates, rearranging in increasing order, and ranging evaluation values in increasing order; and an end condition step (Step4) based upon an evaluation value, and also has a re-selection step (Step5) of selecting a next structure candidate when an end condition is not met, a structure candidate having minimum evaluation value order being determined as an optimum feedback controller.SELECTED DRAWING: Figure 1
【課題】最良の評価値を与えるFB制御器の最適構造を、少ない探索回数で決定し、FB制御器設計を効率化できる設計方法を提案する。【解決手段】最適化アルゴリズムを適用し、フィードバック制御器の構造候補を選択する選択ステップ(Step1)と、選択された構造候補の各々にパラメータ設計を行うパラメータ設計ステップ(Step2)と、設計パラメータに対する評価値により、選択された構造候補に順位付け、昇順に並び替え、昇順による評価値順位の評価値順位ステップ(Step3)と、評価値に基づく終了条件ステップ(Step4)と、を備え終了条件が満されないときは、次の構造候補を選択する再選択ステップ(Step5)を有し、評価値順位が最小である構造候補を最適なフィードバック制御器とする。【選択図】図1 |
