Abstract
This paper provides a new and powerful tuning method of controllers in the two-degree of freedom control scheme in the sense of that we require only one-shot experimental data of the closed loop. The key concept of our method is to use the fictitious reference (From this reason,we refer to our method as fictitious reference iterative tuning (FRIT)). Moreover, by using this tuning method, we also provide a new and powerful identification method in the sense of that we require only one-shot closed experimental data. Finally, we give an experimental result in order to show the validity of the proposed method in this paper.
