本研究では,これまでのネットワーク化制御系における最適化手法を基盤に,機械学習に代表される最新の手法によって不確定要因の推定と補償を融合し,情報・人間・機械が結合する超スマート社会の基盤技術を担うネットワーク化制御系の理論を体系化する.また,その手法の有効性を複数マシンの分散協調制御の実験によって明らかにする.

Outline of Final Research Achievements

In 2020, we proposed a method using reinforcement learning for data quantization, data missing, and data transmission scheduling in networked control systems, and confirmed its effectiveness in experiments. 2021, in addition to scheduling using reinforcement learning, we proposed a method based on matrix inequalities using sparse matrices, and showed its effectiveness in simulations. In 2022, we proposed a method of missing estimation and delay guarantee in real-time using machine learning and reinforcement learning, and confirmed its effectiveness in experiments. and optimal control in real-time.

Academic Significance and Societal Importance of the Research Achievements
