| Outline of Final Research Achievements |
A motion-controlled ship with absorbing wave energy was developed. The ship consists of floats, a cabin, and suspensions. Absorption of wave energy was maximized by maximum power point tracking method, and the motion of the cabin was controlled by a skyhook control. The motion of floats was calculated by a strip method. Using the calculated hydrodynamic parameters, a control program including the maximum power point tracking method and the skyhook control was developed. Parameters such as resistance values for wave energy absorption and motion control were determined assuming the regular waves. The results of water tank testing agreed well with those of simulation using the control program for wave energy absorption and the motion of the cabin.
