Abstract

In this study, the experimental test results are given to confirm the control efficiency of the linear control algorithm used for designing the active mass dampers(AMD) which are supposed to be installed at Incheon international airport control tower. The comparison between the results from test and numerical analysis is conducted and it was observed that the AMD showed the control performance expected by the numerical model. The effects of the gain scheduling and constant-velocity signal added to the control signal calculated by the algorithm is identified through the observation that the AMD always show behavior within the given stroke limit without any loss of the desired control performance. The phase difference between the accelerations of the structure and the AMD were almost close to 90 degree, which implies that the AMD absorbed the structural energy effectively.

본 연구에서는 인천공항 제2계류장 관제소에 설치될 예정인 AMD에 선형제어알고리즘인 속도피드백 알고리즘을 적용하여 제어효율 및 안전성을 평가하였다. 공장성능시험 결과와 수치해석 프로그램의 해석결과를 비교하여 AMD가 설계의도대로 제어를 수행하는지 여부를 분석하였다. 또한 제어알고리즘에 의한 순수제어력에 추가되는 게인스케줄링과 원점보정신호가 제어력에 미치는 영향을 실험을 통해 확인하였다. AMD의 성능시험 결과 게인스케줄링과 원점보정신호는 제어효율에 큰 영향을 미치지 않음을 확인하였으며, 구조물에 큰 외력이 작용하는 경우에 발생하는 AMD 질량체의 과도한 이동으로 인해 구조물에 손상을 입힐 수 있는 문제에 대한 안전성을 검증하였다. 추가적으로 제어효율지수를 도입하여 AMD의 제어 상태를 모니터링한 결과, 적용된 알고리즘이 효과적으로 구조물을 제어함을 확인하였다.
