On the various problems concerning to the ship motions and their control in Waves, we have engaged in both from theoretical and experimental aspects. The followings are the main results obtained through these researches:1) The design of a wave maker which is intended to produce any wished wave form and spectrum at appropriate point in a towing tank, is done. The implementation was also done according to the design.2) A remote control system of the wave maker was made between a personal computer on the towing carriage and the wave maker. All settings and control are satisfactorily done through the system.3) Various methods producing irregular waves were investigated and applied to the wave maker. Some experiments were done to estimate "blue seas" upon a deck. Snake type(multi-plunger type) wave maker was also investigated mainly from the theoretical calculation and simulation.4) Remote control and measurement system was proposed to do various model tests such as capsizing in the following seas and roll-yaw stabilization stem. The system is utilizing a microcomputer installed in the model ship, vertical gyro also in the model ship, personal computers on the towing carriage and two video cameras.5) Transverse wave pattern analysis method was proposed and applied to analyze unsteady wave field. This method my be applicable to estimate wave resistance increase of a ship.6) So-called wave damping was fully investigated by experiments using multi-hull platform.7) Fuzzy control and neuro control were applied to heaving and rolling control of a ship, mainly from its stability with comparizon of PD control.

本文从理论和实验两个方面对船舶在波浪中的运动及其控制的各种问题进行了研究。1）设计了一种能在拖曳水池中适当位置产生任意波形和频谱的造波机。2）设计了造波机的远程控制系统，由牵引车上的PC机与造波机进行远程控制。研究了各种不规则波的产生方法，并将其应用于造波机中。做了一些实验来估计甲板上的“蓝色海洋”。主要从理论计算和仿真两个方面对蛇形（多柱塞）造波机进行了研究。4）设计了遥控测量系统，可进行随浪倾覆、横摇-偏航稳定杆等多种模型试验。该系统利用安装在模型船上的微型计算机、安装在模型船上的垂直陀螺仪、安装在拖架上的个人计算机和两台摄像机。5）提出了横向波型分析方法，并将其应用于非定常波场分析。该方法可用于估算船舶的兴波阻力增加量。6）通过多体平台试验，对所谓的波浪阻尼进行了充分的研究。7）将模糊控制和神经网络控制应用于船舶的升沉和横摇控制，主要从稳性方面与PD控制进行了比较。
