Abstract
In this paper, we presents a scheme for the parameter estimation and optimal control scheme for apparatus of container crane system. For parameter estimation, first, we construct the open loop of the container crane system and estimate its parameters based on input-output data, a real-coded genetic algorithm(RCGA) and the model adjustment technique. The RCGA plays an important role in parameter estimation as an adaptive mechanism. For controller design, state feedback gain matrix is searched by another RCGA and the estimated model. The performance of the proposed methods are demonstrated through a set of simulation and experiments of the experimental apparatus.
컨테이너 크레인의 수학적 모델 정확도는 모델 내부 파라미터 값의 정확도에 의해 결정되나, 기술적 혹은 환경적인 문제로 내부 파라미터의 정확한 값을 알지 못하는 경우가 빈번히 발생하기도 한다. 이 경우에는 시스템의 입
