| Research Abstract |
The aim of This study is development of ship position control and automatic navigation system. But it is still difficult to develop a ship position control system considered many aspects. So we started this study from the case of navigation in harbor especially berthing, that is a burden to a navigator, and in that case the navigation supporting system by automatic positioning is vary effective.
Captive model test was usually carried out to estimate a ship maneuverability. But a low speed test is difficult in present captive model test technique. So we made a free-running test instead of a captivemodel test. Firstly we carried out a real ship test. Free-running test was not attached importance, since its problem in analysis was pointed out. We tried to break through by devising test items and developing a statistical analysis utilizing database.
In a real ship test, we developed experiment system by using a kinematic GPS, which is a satellitic positioning system with high accuracy. In a model test, we developed a experiment system with a video positioning analyser and air fans for moving model ship supposed tug boats.
About ship position control, we investigated neural network control system and made a simulation for a berthing, and designed automatic berthing control system. Next subject is generalization to many aspects.
Finally, we examined possibility to equip this position control system into a navigation supporting system.
