무인잠수정의 자율 운항기술을 연구함에 있어 가장 근본적인 기술 중의 하나가 소나를 이용해 실시간으로 획득되는 해저지형이나 장애물에 대한 정보를 이용하여 임무수행을 위한 3차원 경로계획을 수립하는 것이라 할 수 있다. 무인잠수정의 3차원 경로계획은 장애물 회피 제어기술을 기반으로 유도제어, 동역학 모델, 해양환경 및 탐지소나 모델 등이 다양하게 고려되기 때문에, 경로계획을 연구 개발함에 있어 알고리즘을 검증하기 위한 시뮬레이션 시스템이 필요하다. 본 논문에서 개발한 시뮬레이션 시스템은 다양한 해양환경을 설정할 수 있고, 설정된 장애물들을 회피하여 경유지를 지나 목적지까지 이동하는 무인잠수정을 C++와 OpenGL을 이용하여 가시화함으로써 3차원 경로계획 알고리즘을 검증할 수 있다. 또한 어떠한 개발환경에서 연구된 무인잠수정의 경로계획 알고리즘도 검증할 수 있는 범용성을 제공한다.

Mine countermeasure missions(MCMs) may induce the loss of human and ship because of the covert of mine. In recent years, unmanned underwater vehicles(UUVs) have emerged as viable technical solution for conductimg underwater search, surveillance, and clearance operations in support of mine countermeasure missions because of her autonomy and long time endurance capability. This paper introduces a technical approach to mine countermeasure mission effectiveness analysis and presents some simulation-based analysis results for engineering of the UUV system definition which could be support analysis of alternatives for system definition and design.

In recent years, unmanned underwater vehicles(UUVs) have emerged as viable technical solution for conducting underwater search, surveillance, and clearance operations in support of mine countermeasure missions(MCMs) because of her autonomy and long time endurance capability. It is necessary for UUV for MCM system design to define system specification from various configuration alternatives. This paper introduces a simulation model for mine countermeasure mission effectiveness analysis and presents some simulation results under various tide conditions for validation of the proposed simulation model.

This paper represents the experimental identification of a finite-dimensional dynamical plant model for the HEMIRE Remotely Operated Vehicle. The experiments were conducted during sea trials in the East Sea in October 2006 and peer testing by the South Sea Research Institute in January 2007. A least-squares method was employed to identify decoupled single degree-of-freedom plant dynamical models for the X, Y, Z and heading degree-of-freedom from experimental data. The performance of the identified plant dynamical model was evaluated by directly comparing simulations of the identified plant model to the experimentally observed motion data from the actual vehicle.
