Abstract

This paper introduces a hovering-type autonomous underwater vehicle (AUV) developed for research and its fundamental motion performance results obtained by simulation and field test. The AUV can control its motion in four degrees of freedom (DOF) by means of its horizontal and vertical thrusters, and it is designed to provide a test-bed that facilitates ease of operation and experimentation. Prior to the field tests, six DOF equations of motion are developed, and a simulation program is constructed using MATLAB and Simulink to verify the essential motion performance of the designed vehicle. Furthermore, a proportional-integral-derivative (PID) controller and fuzzy PID controller are designed, and their performances are verified through a simulation. Field tests are performed to verify the motion performance of the AUV; way-point tracking is executed by the PID and fuzzy PID controllers. The results confirmed appropriate control performance under current disturbances.

본 논문은 연구용으로 개발된 호버링 타입 무인잠수정을 소개하고 기본적인 운동성능에 대한 시뮬레이션 및 실해역 실험결과를 서술하였다. 본 연구에서 개발된 무인잠수정은 수평 및 수직 추진기를 이용하여 4자유도 운동을 제어 할 수 있으며, 실험이 용이하고 운용하기 쉬운 구조의 테스트 베드용으로 설계하였다. 본 논문에서는 실해역 실험 이전에 무인잠수정의 6자유도 운동방정식을 전개하고 Matlab/Simulink를 이용하여 시뮬레이션 프로그램를 구성하였으며, 이를 통하여 설계된 무인잠수정의 기본적인 운동성능을 확인하였다. 또한 무인잠수정이 주어진 임무를 수행하기 위하여 PID 제어기 및 Fuzzy PID 제어기를 설계하였고 설계된 제어기의 성능을 시뮬레이션을 통하여 확인하였다. 실제 제작된 무인잠수정의 운동성능을 확인하기 위해 실해역에서 실험을 수행하였으며, 설계된 PID 제어기 및 Fuzzy PID 제어기를 이용하여 경유점 제어를 수행하였고 그 결과 조류 외란이 존재하는 실해역 상에서 적절한 제어성능을 확인 할 수 있었다.
