| 摘 要： | 动力定位系统是一种闭环控制系统，采用推力器来提供抵抗风、浪、流等作用在船上的环境力，从而尽可能使船舶保持在海平面要求的位置上。在传统模糊控制的基础上，将遗传算法引入模糊控制器的设计当中，根据已知的模糊控制规则，对模糊隶属度函数自动寻优，该方法用于船舶动力定位中，对船舶纵向运动进行控制与仿真，仿真结果证明遗传算法优化的有效性。

| Abstract: | The dynamic positioning system is a closed loop control system which resists against the disturbance by wind, wave, and current with the help of thrusters on the vessel. Genetic algorithm uses in fuzzy controller design. Using this mew method, fuzzy membership function can be optimized automatically according to known fuzzy control rules. This method is used in dynamic positioning system of ships. The vibration along the forward direction is controlled and simulated. The result shows that genetic algorithm is effective for optimization. |
