Abstract

Disclosed are a control device of a free-running system for a water tank-based motion model test and a method thereof. The control method of a free-running system for a water tank-based motion model test includes the following steps of: measuring the speed of a towing carriage; measuring the 6 degrees-of-freedom motion of a model vessel; determining whether the measured speed is stable; performing the first proportional integral derivative (PID) control on the rpm of a propeller of the model vessel such that the model vessel′s speed increases to a preset target; determining whether the motion of the model vessel is stable by using a surge of the measured 6 degrees-of-freedom motion if the measured speed is not stable; performing a second PID control on the rpm of the propeller of the model vessel such that the model vessel maintains the target speed as long as the motion of the model vessel is stable; and performing a third PID control on the rpm of the propeller of the model vessel if the motion of the model vessel is not stable.

수조기반 운동 모형시험용 자유항주 시스템의 제어 장치 및 방법이 개시된다. 수조기반 운동 모형시험용 자유항주 시스템의 제어 방법은, 예인전차의 속도를 계측하는 단계, 모형선박의 6자유도 운동을 계측하는 단계, 계측된 속도가 안정(stable)한지 여부를 판단하는 단계, 계측된 속도가 안정한 경우, 모형선박이 미리 설정된 목표속도까지 상승하도록 모형선박의 프로펠러(Propeller) 회전속도에 대한 제1 PID(proportional integral derivative) 제어를 수행하는 단계, 계측된 속도가 안정하지 않은 경우, 계측된 6자유도 운동 중 전후동요(surge)를 이용하여 모형선박의 운동이 안정한지 여부를 판단하는 단계, 모형선박의 운동이 안정한 경우, 모형선박이 목표속도를 유지하도록 모형선박의 프로펠러 회전속도에 대한 제2 PID 제어를 수행하는 단계 및 모형선박의 운동이 안정하지 않은 경우, 모형선박의 프로펠러 회전속도에 대한 제3 PID 제어를 수행하는 단계를 포함한다.
