遗传算法在船舶动力定位模拟器推力系统中的应用
|
摘要
动力定位系统是大型船舶辅助推力系统,其利用各类传感器、GPS及水声处理器计算海洋中变幻莫测的风、浪、水流作用力,提供对应的推力进行抵消,从而保障船舶按照预定的航速、航向运行。本文研究了船舶动力定位模拟器结构,利用遗传算法对各类传感器采集数据进行融合,对模拟器数据故障进行分析,最后验证了算法有效性。
Dynamic positioning system is a large-scale ship auxiliary thrust system. It uses various sensors, GPS and underwater acoustic noise processors to calculate the unpredictable forces of wind, wave and current in the ocean, and provides corresponding thrust to offset them, so as to ensure that the ship runs at a predetermined speed and course. In this paper, the structure of ship dynamic positioning simulator is studied. The data collected by various sensors are fused by genetic algorithm, and the data faults of the simulator are analyzed. Finally, the validity of the algorithm is verified.
