| 要約 |
制御通信技術は，医療，ヘルスケア，金融，防災・減災，建造物の保守や屋内環境制御，生産現場といった幅広い応用分野を持ち，また高度交通システムやスマートグリッド／スマートコミュニティ実現のためにも不可欠である．本基調講演では，この制御通信について，その意義と面白さを主に学術面から概説する．具体的には制御において通信の振る舞いを考えることは，制御系を確率的に捉えることになることを述べる．また，制御通信が従来の通信とは異なる要求要件を持つものであることを示し，上位層の品質で通信品質を評価できること，さらに複数層一括最適化ができることを述べる．また従来の情報通信がともすれば軽視してきた時間に関わる尺度で通信品質を考える必要性を説明する．さらに，情報の鮮度を考慮した情報理論，制御通信専用のプロトコルの必要性，複数機器制御等の制御通信に関わる話題を概説する． |

| Summary |
Control communications have a wide variety of applications including medical and healthcare systems, financial systems, disaster protection/recovery, building management, manufacturing systems, and robots/humanoid, and a key technology for large scale systems and systems of systems such as intelligent transportation systems and smart grid/community systems. This keynote address illustrates important and interesting features of the control communications, mainly from an academic viewpoint. At first, it is explained that a control system has to be regarded as a probabilistic system when imperfectness of control communications is considered. Then differences of the requirements for conventional and control communications is clarified. It is noteworthy that the performance of communication layer can/should be evaluated by using the quality of its upper layer, i.e., control layer, and cross-layer optimization of control and communication layers is possible. In addition, new measures/viewpoints of communication qualities are introduced. Information theory of freshness of information, necessity of communication protocols for control, and simultaneous control of multiple objects are briery outlined as examples of interesting topics on control communications.
