... ABSTRACT The control effect of traditional PD controller is poor, because AUV hydrodynamic model is a typical nonlinear system. This paper uses fuzzy control theory to design fuzzy controller. Based on AUV nonlinear hydrodynamic model, four controllers are designed: PD controller, Mamdani...

... by coupling a hydrodynamic model with a genetic algorithms solver. Optimization is performed for three near-shore sites in the Aegean Sea, Greece. Optimum layouts are obtained considering part of or the whole wall length, available for the PAs' sitting. The effect of the incident wave direction on the optimum...

... In the maritime domain, real-time unified hydrodynamic models are not only used for education and training in full bridge simulators (International Maritime Organisation, 1995). They are also being recently used in navigation systems for aiding ship position estimations (Bryson & Sukkarieh, 2006; Crocoll et...

... ABSTRACT Until 2019 the Rules of Russian Maritime Register of Shipping (RS) had only regulated design ice impact loads on inclined hull sides. These regulations are based on a hydrodynamic model of ship hull/ice interaction. At present large-size vessels operating in the Arctic seas have full...
