dc.description.abstract | 등가정하중법을 이용하여 제어시스템과 구조물의 설계를 동시에 수행하는 새로운 최적설계 방법을 제안한다. 많은 현대 구조물들은 제어시스템을 포함하고 있으며, 구조물은 제어시스템에 의해 작동한다. 두 시스템은 서로 영향을 주고 받기 때문에 구조물과 제어시스템의 관계를 서로 독립적이라 할 수 없다. 따라서 이 두 분야는 통합적 방식으로 동시에 설계가 이루어져야 한다. 또한 제어시스템 구조물은 시간영역에서의 성능이 중요하기 때문에 과도응답해석을 고려한 최적설계가 이루어져야만 한다. 제어시스템 구조물의 최적설계 과정 중 고려하는 제한조건도 시간영역에서 정의한다. 제어시스템 구조물 설계의 이러한 특징 때문에 작은 규모의 문제도 매우 큰 규모의 최적설계문제로 변환된다. 본 연구에서는 대형 규모의 제어시스템 구조물 문제를 해결하기 위하여 새로운 등가정하중법을 제안한다. 이 방법은 구조변수뿐만 아니라 제어변수를 다룰 수 있는 최초의 등가정하중법이다. 제어힘을 포함한 유한요소 지배방정식과 동적반응 최적설계 문제를 위한 정식화를 정의한다. 동해석으로부터 산출된 등가정하중을 이용하여 선형정적반응 최적설계를 수행하며, 이때 제어힘은 최적설계 과정에서 설계변수로 고려한다. 제어힘 설계를 위해 형상 변수를 이용하는 몇 가지 방법에 대하여 소개하며, 여러 가지 예제를 통하여 제안한 방법의 유용성과 효율성에 대하여 검증한다.|An optimization method is proposed for the simultaneous design of structural and control systems using the equivalent static loads. The two structural and control systems are not completely independent and need to be considered in a unified fashion. Furthermore, an integrated system design is unavoidable to exhibit a good performance in the time domain. The analysis for the integrated system is conducted for the transient-state in a dynamic manner. The constraints for the structural and control systems are defined in the time domain as well. Therefore, a physically small scale problem in structural analysis easily becomes quite a large scale in an optimization problem. A new equivalent static loads (ESLs) method, which deals with the structural design variables as well as the control design variables, is proposed to solve physically large scale problems. A finite element dynamic equation is defined with control forces and a dynamic response optimization problem is formulated. Linear static response optimization is carried out with the ESLs. The control forces for the linear static response optimization are considered as design variables. Shape variables are utilized to handle the design variables for the control forces. Several examples are solved to validate the proposed method.; An optimization method is proposed for the simultaneous design of structural and control systems using the equivalent static loads.
