Taking the ship of “Mariner” for example, gives its steering characteristics under uniform ocean wind and fluid. Fuzzy control theory is applied to the control of ship maneuvering. The reasonable control rules are formed. The ship′s head angle and transverse position are selected as the fuzzy control parameters. The control results show that, when sailing under ocean wind and fluid, it is a good method to keep ship′s sailing direction and route by fuzzy control. The method can not only control the head turning, but also keep a ship in the original sailing range.
