データ駆動による安定余裕の下界推定情報に基づく安定化制御器設計

抄録

In this paper, we propose a stabilizing controller design method to use the lower bounds of the stability margins estimated by a data-driven method in a situation where a plant is unknown. To design a stabilizing controller, we derive a theorem which gives a class of a stabilizing controller. By using this theorem, we can design a controller to stabilize the closed-loop system without the mathematical model of a plant. In the numerical example, we estimate the lower bounds of the stability margins and design a stabilizing controller with only this.
