This paper proposes a practical method to identify the process dynamics for an integral process with dead-time, under continuous self-excited oscillation. It is assumed that the limit cycle is mainly caused by either the nonlinear property, dead-time …

This paper proposes a practical sampled-data I?P controller design for integrating processes. The controller struc-ture, derived from model predictive control theory, is a simple I?P controller. Application to predictive functional …
モデル予測制御理論に基づいた積分プロセスに対するサンプルI-Pコントローラの設計方法を提案した．導出された本コントローラの構造は比例先行型のI-P制御の単純な形式に帰結した．この方法はPFC（Predictive Functional Control）にも応用可能である．本制御則は，その導出において積分プロセスモデルをモデル予測制御の基本的な形態である1段予測の形式で表現することで得られる．本提案手法ではコントローラの比例項は制御量変化を止め，積分項は目標値への収束速度を決める役割を担う．またパ …
Constrained optimal control using an industrial three term controller is remarkably challenging to achieve, even for processes with simple dynamics. In this paper, an optimization based practical approach for the design of an industrial PI controller …
