本論文主要研究工作包括：對羅經和多普勒計程儀推算輔助導航系統的工作原理，及減小定位誤差的兩種方法和幾種軌跡進行了研究；對影響多普勒計程儀測速誤差的各個方面進行了綜述；最後對多普勒計程儀水池試驗的數據進行了處理，得出所要結論。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術的優越性，嘗試將智能化控制技術用於船舶操縱運動模擬，初步探索了將現代控制理論和智能技術融入船舶操縱預報、模擬的研究方法，提出了用於船舶操縱運動模擬的線性神經網路（ lnn ） 、神經網路遞推模型（ nnrm ）和nnrm 、交錯航跡距離（ cte ）和視距（ los ）混合控制器模型三種控制模型：並將控制模型的理論研究應用到實船試驗數據分析、計算，將模擬結果與實際的試驗結果作了比較。Aerospace series - cables, electrical, aircraft use - test methods - part 603 : resistance to wet arc tracking
航空航天系列.飛機電纜.試驗方法.第603部分:耐濕電弧痕跡性The chapter 3 and 4 are the core of this dissertation. under the theory of ship manoeuvre capability, it calculates the moving track and strap especially affected by wind and current. base on the analysis of those parameter, the basic theory is provided on navigational safety in the bridge waters
以試驗及調研的數據為依據，運用第三章建立的數學模型分析、計算船舶在橋區運動的軌跡及航跡帶，重點計算在風、流等因素影響下的船舶橫向漂移量，並對船舶在橋區運動軌跡方程的參數及橋區影響船舶橫向漂移量的因素進行分析，為船舶在橋區安全航行提供理論依據。Aerospace series - cables, electrical, aircraft use - test methods - resistance to wet arc tracking
航空航天系列.飛行器用電纜.試驗方法.耐濕弧光痕跡性能The study comes from two projects - " the practical experiment of ship navigation and the simulation study of the shu - tong yangtze river road bridge " and " the study on the ship navigation of the yichang yangtze river railway bridge ". the data is from these practical experiment which includes z - model experiment of sea - going vessel and fleet, turning motion experiment, stroke experiment and encounter experiment between sea - going vessel and fleet. based on those, it calculates the track of the ship in the navigational waters according to the maneuverability and the response equation
