초록

본 연구에서는 지진하중을 받는 인접한 건물의 진동제어를 위한 준능동 제어장치의 제어성능을 검토하였다. 준능동 제어장치로는 MR 감쇠기를 사용하였다. MR 감쇠기로 연결된 인접한 건물을 효과적으로 제어하기 위하여 퍼지제어알고리즘을 사용하였다. MR 감쇠기로 연결된 인접한 건물의 제어시 한쪽 건물의 응답을 저감시키는 것은 다른 한 쪽 건물의 응답을 증가시키는 효과를 가져온다. 따라서 연결된 건물의 제어는 서로 상충되는 특성이 있기 때문에 다목적 최적화문제로 귀결된다. 따라서 본 연구에서는 다목적 유전자알고리즘을 사용하여 MR 감쇠기를 제어하는 퍼지제어알고리즘을 최적화하였다. 수치해석을 통하여 준능동 MR 감쇠기를 이용한 인접건물의 연결제어효과를 검토하였고 매우 우수한 성능을 나타내는 것을 확인하였다.

The vibration control performance of a semi-active damper connected to adjacent buildings subjected to seismic loads was investigated. The MR damper was used as a semi-active control device. A fuzzy logic control algorithm was used for effective control of the adjacent buildings connected to the MR damper. In the buildings control coupled with a MR damper, the response reduction of one building results in an increase in the response in another building. Because of these conflict characteristics, multi-objective optimization is required. Therefore, a fuzzy logic control algorithm for the control of a MR damper was optimized using a multi-objective genetic algorithm. Based on numerical analyses, the semi-active fuzzy control of MR damper for adjacent coupled buildings can provide good control performance.
