초록

제안한 Taylor모델 개념은 단지 입출력 데이터만을 이용하여 제어기를 설계하기 위해 사용되는데, Taylor모델의 매개변수는 입출력 데이터들을 사용하여 추정되고 제어기는 Taylor모델을 통하여 얻어진다. Taylor모델 근사화의 정확성은 관측창의 크기와Taylor모델의 차수가 커짐에 따라 좋아진다. Taylor모델을 이용한 전력계통의 안정화를 위해 LQR 제어기가 제안되고 컴퓨터 시뮬레이션을 통해 기존의 방법과의 성능을 비교한다.

The Taylor model concept is introduced to design a controller with input and output data only. The parameters in Taylor model can be estimated using the input and output data and a controller can be designed based on Taylor model. The accuracy of Taylor model approximation can be improved by increasing the observation window and the order of Taylor model. The LQR method is applied to Taylor model to design power system stabilizers (PSS), and compared with the conventional PSS.
