Abstract

This paper deals with adaptive fuzzy logic controller design to achieve proper dynamic response of a composite thin-walled beam with a tip mass. In order to check the effectiveness of this controller, three different types of control logic are selected and applied. The adaptive control capabilities provided by a system of piezoactuators bonded or embedded into the structure are also implemented in the system. Results show that the fuzzy logic controller is more effective than the proportional or velocity feedback controller for the vibration control of composite thin-walled beam with a tip mass.

본 연구에서는 끝단에 질량이 부착된 복합재료 박판 보의 동특성을 제어하기 위하여 퍼지 알고리즘을 이용한 적응 제어 기법에 대하여 고찰하였다. 적응제어기법을 구현하기 위해 감지기와 작동기의 역할을 할 수 있는 압전재료를 구조물의 중립면상에 삽입하였다. 끝단 질량이 변하는 경우, 비례제어 및 속도제어와 비교해 볼 때, 퍼지 알고리즘을 이용한 제어 기법이 복합재료 박판 보의 동적응답제어에 우수한 성능을 보였다.
