主要研究內容包括:一、總結分析了當前水下導航的常用方法和不足之處,指出基於航位推算的導航方法,存在著最大的問題就是導航誤差的積累問題,如果沒有修正系統,這種方法很難滿足使用要求;其次指出基於聲學的導航方法,造價昂貴,導航范圍有限,難以滿足自主水下航行器大范圍導航的需求;二、總結了當前水下地形輔助導航的主要技術路線,一是基於地形高程的匹配方法,這是當前研究的重點;二是基於地形圖像的匹配方法,由於缺乏良好的圖像傳感器,和可用的海底圖像地圖,目前這種方法還有待研究發展;三、將兩種地形高程匹配的常用方法應用到自主水下航行器上:以相關演算法為前提的地形輪廓匹配( tercom )方法和以卡爾曼濾波為基礎的桑迪亞慣性地形輔助導航( sitan )方法,前者演算法簡單可靠,但是導航精度不高,後者雖然精度比較高,但存在著演算法較為復雜、有可能發散和出現奇異值等問題。In the paper, the effects of mooring position, towing line length and towing speed on the course stability and towline tension are analyzed firstly for the ship towing system in calm water
由於在實際海況中,除了受到風、流的影響之外,波浪作用力所造成的影響更為巨大,在波力及波力矩的作用,船隻航行的航向穩定性與靜水中相去剩甚遠。In 1596, english navigator sir francis drake died off the coast of panama ; he was buried at sea off puerto bello, panama, in a lead coffin

從本文中可以看出,將觀測器和作動器相結合可以對航行於波浪中的船舶結構振動實施適時的主動控制,並且裝上作動器不但不會影響船體本來的性能,而且可以增加其抗波浪砰擊能力,因此主動控制方法在船舶結構砰擊響應控制方面的應用和研究應該給予一定的重視。Hirayama t, et al. directional ocean wave measurement utilizing running ship motion and radar images [ j ]. 1997, omae - volume, safety and reliability asme 1997
