摘　　要：本文研究了船舶动力定位中模糊控制的应用问题,探讨了模糊控制中隶属函数和模糊规则的具体制定,并应用可变论域的思想对模糊控制器进行改进。对船舶的纵向运动进行了控制与仿真,并且做了比较与分析。仿真结果表明,改进的模糊控制器能对船舶的动力定位实施更有效的控制。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.
