ship trajectory meaning in English

船行轨迹

To apply neural networks to the simulation of ship maneuvering motion , an nnrm ( neural network recursive model ) is designed and used to simulate a serial full - scale tests conducted in yangtze river and the comparison between simulated results and the measured ones is satisfactory . ship trajectory tracking is a well - known maneuvering problem with an increasing practical and theoretical interest . but the real - world tracking applications encounter a number of difficulties caused by the presence of different kinds of uncertainty due to the unknown or not precisely known system model and environmental effects
本文利用智能控制技术的优越性，尝试将智能化控制技术用于船舶操纵运动模拟，初步探索了将现代控制理论和智能技术融入船舶操纵预报、模拟的研究方法，提出了用于船舶操纵运动模拟的线性神经网络( lnn ) 、神经网络递推模型( nnrm )和nnrm 、交错航迹距离( cte )和视距( los )混合控制器模型三种控制模型：并将控制模型的理论研究应用到实船试验数据分析、计算，将模拟结果与实际的试验结果作了比较。
