Abstract

The primary object of this study was to develop the control algorithm and program for automatic submersible buoy which is free to move vertically within the water column by adjusting weight and buoyancy forces by air control. The experiment was performed to validate the usefulness of the program in the indoor water tank. In the experiment, the automatic submerging and surfacing of the buoy were controlled by water-pressure gauge and air control system. The buoy is raised by injecting compressed air from a compressor and then is lowered by releasing the air. The submerging and surfacing characteristics of the buoy calculated with the numerical model were similar to measurements obtained with the experiment. It was concluded that the algorithm and program could be useful in analyzing various parameters and submerging mechanisms required to design new type of automatic submersible fish cage system.

자동 부침식 가두리 시설을 개발하기 위해 가두리 시설을 구형 부자로 단순화하여 이것의 자동 침하 및 상승 관련 제어 알고리즘 및 프로그램을 개발하였고 실내 수조 실험을 통해 그 유용성을 확인하였다. 또한 기존 연구 결과의 수치와도 비교 분석함으로써 기존 연구의 수치 모델 결과의 유용성을 재확인하게 되었다. 그리고 실물 실험에 대한 선행 연구로써 많은 변수들과 부력에 대한 비선형적인 메커니즘을 제어를 통해 극복하였으며, 이는 실물 실험에 있어 중요한 요소로 작용될 것이다.
