Outline of Research at the Start

電力システムや交通システムに代表される,物理システムと情報システムが相互結合したシステムはサイバーフィジカルシステムと呼ばれている.通信負荷や消費電力の軽減に向けて,必要なときだけ計測値の収集や制御入力の更新を行うイベントベースト制御の開発が重要である.本研究では,イベントベースト制御の理論構築,セキュアな実装方法の開発,および車群制御への応用に取り組む.以上の取り組みにより,Society 5.0の実現に向けた基盤を確立する.

Outline of Annual Research Achievements

サイバーフィジカルシステム(CPS)とは,物理システムと情報システムが相互結合したシステムである.電力,医療,農業,モビリティなど多くの分野に応用されている.CPSに対する制御手法の確立を目的として,さまざまな手法を開発した.
まず,セキュアな制御方法の確立を目指して,電力ネットワークの分散状態推定におけるサイバー攻撃の検出方法を提案した.計算途中の暫定的に推定値を活用することで,従来方法では検出できなかったサイバー攻撃を検出することが可能になった.
次に,車群制御に関連して複数エージェントの制御問題に取り組んだ.ある領域を複数エージェントで監視する監視問題では,混合整数計画問題を解くことで軌道を求める方法を提案した.中国人郵便配達問題を利用した可解条件も導出した.制御仕様が時相論理で与えられている制御問題では,強化学習を用いた解法を導出した.時相論理とは,時間とともに命題の真偽が変化する論理である.複雑な制御仕様を記述することが可能になる.アグリゲータを導入することで,学習が効率的に進むことを明らかにした.また,報酬分配についても新しい方法を検討した.最後に,複数エージェントによるオンライン配送計画問題を検討した.通常の配送計画問題では注文が入っている時間区間のみを考える.提案手法では,需要予測を活用して,より長い時間区間の最適化を考える.需要が高い荷物の発送場所に事前にエージェントを移動させることで,効率的な配送計画が実現可能になる.
