| Abstract: | The fuzzy logic controller used for ship dynamic positioning system is studied and the design of membership functions and fuzzy rules are discussed in this paper. The idea of variable domain is applied to improve the fuzzy logic controller. The control and simulation for a ship logitudinal motion are performed by means of the two controllers, one is the normal controller, another is the improved controller. Then the results of the two different ways are compared and analyzed. It shows that the result of the improved controller is better than that of the normal controller for the ship dynamic positioning systems. |
