Outline of Final Research Achievements

Data-driven design, in which a simple controller such as a PID controller is adjusted off-line using the plant's input-output response, is not suitable for unstable and oscillatory plants. To deal with this problem, a two-step method was proposed in which the plant is stabilized by model-based design and data-driven design is applied to the closed-loop system. In the model-based design, an implementation method of stabilized controllers that are suitable for data-driven design was presented. In data-driven design, a method for drawing PID gain sets in parameter space and a method for evaluating system gains using input-output response data were presented, and the conventional design method was extended to multi-input-output systems. Numerical experiments showed the usefulness of the two-step method.

Academic Significance and Societal Importance of the Research Achievements

モデルベーズド設計の成果によりオーバーシュートの小さい目標値応答を与えるロバスト安定化制御器の簡便な実装が可能となり,データ駆動設計の成果によりステップ応答を用いたシステムゲインの下界の評価や既存のデータ駆動設計のゲイン調整法の多入出力系への拡張が可能となった。モデルベーズド設計を併用することでデータ駆動設計を不安定,非最小位相系などを含む幅広い制御対象に適用可能となった。
