Abstract

In this paper, an integrated optimum design method for hybrid structural control system is studied. Not only the distribution and the capacity of passive devices but also those of active devices, and the controllers are treated as design variables in the proposed approach. Multi-objective optimization problem is formulated by using the preference function, which is newly defined in this study. Genetic algorithm is adopted as a numerical searching technique in order to simultaneously find the optimum solutions. The validity of the proposed method is verified through the example designs and the numerical simulations of an earthquake excited multi-degrees-of-freedom structure.

복합구조제어시스템의 동시최적설계방법에 관하여 연구하였다. 여기에서는 수동제어장치 뿐만 아니라 능동제어장치의 배치와 용량, 제어기 등이 설계변수가 되며 설계인자들의 만족도를 나타내는 선호도함수를 정의하여 이를 이용하여 최적화문제를 정식화한다. 또한 수동 및 능동제어장치의 설계변수로부터 동시에 최적해를 찾아내기 의한 수치적 방법으로 유전자알고리즘을 사용하였다. 지진하중을 받는 다자유도 구조물의 설계에 및 수치모사를 통하여 제안한 방법의 타당성을 검증하고자 하였다.
