周期的通信制約をもつネットワーク化制御系のモデル化と構造的性質 Modeling of a networked control system with periodic communication constraints and its structural properties 河野, 通夫 コウノ, ミチオ Kono, Michio 鈴木, 達雄 スズキ, タツオ 20315352 高橋, 伸弥 タカハシ, ノブヤ Takahashi, Nobuya 高橋 タカハシ Takahashi 伸弥 ノブヤ Nobuya 宮崎大学 University of Miyazaki 佐藤, 治 サトウ, オサム Sato, Osamu 佐藤 サトウ Sato 治 オサム Osamu Suzuki, Tatsuo 佐藤, 治 サトウ, オサム Sato, Osamu 佐藤 サトウ Sato 治 オサム Osamu networked control system, periodic system, controllability and stabilizability, reconstructibility and detectability This paper proposes a new model for a networked control system and considers its structural properties such as controllability, stabilizability, reconstructibilty and detectability. To control a linear time-invariant discrete-time plant via a bus with limited capacity, we introduce a hold device and a communication sequence which follows a given ω-periodic pattern. Incorporating the communication sequences and hold devices into the original plant amounts to extending the original time-invariant state equation to the ω-periodic one which has the higher order. We assume that the communication sequence is admissible. It is shown that controllability and stabilizability of the plant are preserved in the periodic extended system under the assumption that the zeros of the communication characteristic polynomial does not coincide with λ1/ω where λ is the eigenvalue of the plant. On the other hand, reconstructibility（detectability） of the original plant implies that the periodic observability pair of the extended one is reconstructible（detectable） at any time. 計測自動制御学会 2010-02 jpn journal article http://hdl.handle.net/10458/2932 https://miyazaki-u.repo.nii.ac.jp/records/1080 AN00072392 04534654 計測自動制御学会論文集 Transactions of the Society of Instrument and Control Engineers 46 2 97 105 https://miyazaki-u.repo.nii.ac.jp/record/1080/files/517.pdf application/pdf 968.5 kB 2020-06-21
