| Outline of Final Research Achievements |
It has been verified by means of theoretical calculations, experiments and time domain simulations that a “Resonance-Free SWATH” as the oceangoing large fast ship has the superior seaworthiness. Firstly, the unsteady characteristics of lift generated by small control fins were clarified. Secondly, the latent ability of RFS for seaworthiness is not completely made use in the case of PD control acts as the large restoring force. A nonlinear sliding mode control has been applied to make up for deficiencies in PD control. As a result, the effectiveness of the sliding mode control has been confirmed. Thirdly, very small added resistance due to waves of RFS has been discussed. Fourthly, the quality of RFS transportation system has been discussed. The quality regarding the navigation time and the number of slammings are very good. Finally, superior economic potential of RFS transportation system has been clarified.
