초록

본 논문에서는 입력에 시간 지연이 존재하는 삼각구조의 비선형시스템에 대한 출력 피드백 제어방법을 제안한다. 제안한 제어기는 고이득 관측기와 선형제어기로 구성한다. Lyapunov-Krasovskii 정리를 이용하여 점근적 안정도를 보장하는 입력지연의 크기를 유도한다. 마지막으로 제안한 결과의 유효성을 증명하기 위하여 모의실험 예제를 제공한다.

This paper presents the output feedback control design for triangular nonlinear systems with input delay. The proposed controller is composed of a high gain observer and a linear controller. It is shown that by using Lyapunov-Krasovskii theorem, the proposed controller ensures an asymptotic stability for sufficiently small input delay. Finally, an illustrative example is given in order to show the effectiveness of our design method.
