Proposal of Estimation of Closed-loop Response Using Input and Output Data

In data-driven controller tuning methods, we some-times suffer from unexpected behavior of a designed closed-loop system since the response of the designed closed-loop system cannot be evaluated in advance. This paper proposes a method to estimate the response of the closed-loop system by using input and output data of the plant without any plant models. Finally, the effectiveness of the proposed method is confirmed by the simulation and the experiment.
