• And if the heading is not kept , it will be hard to control the vessel , or bring about heavy cost while adjusting the head
  如果不保证艏向，艏向变化幅度较大，调整艏向困难增大，能耗会随之很快增加。
• The plan keeps the heading of the vessel close to mean mfh , and does not keeping controlling the sway direction and surge direction
  该方法始终保持艏向接近平均最优艏向，根据纵向、横向偏差不完全控制纵向和横向，结果证明既相对最节省能量。
• The technique is independent from measurement values and mathematic formula of environment factors , combining the acquiring for mfh and control , attaining fast response and a high degree of accuracy
  该方法不依赖于传感器对环境要素的测量，艏向寻优和控制向结合，响应速度快，准确程度高。
• In this thesis fuzzy control method is applied to dp system . it has solved the problems such as accurate position - keeping , searching for most favorable heading ( mfh ) , auto area keeping control , and has acquired satisfied control effect
  本文将模糊控制应用于船舶动力定位系统，解决了定点定位、艏向寻优，区域保持等问题，取得了令人满意的效果。
• When keeping mfh , the force acting on the vessel in the sway direction is lest , this will be of great importance for saving on energy . a technique of searching for mfh based on fuzzy logic is brought up , which adjusts the heading according to the lateral movement of the vessel
  由于在最优艏向上横向受力最小，对于节省侧推功率具有很重要的意义，所以本文又提出了一种基于模糊逻辑的、根据横向运动进行的自动艏向寻优方法。
• The content of the thesis include many scientific fields , such as nautical mathematics , apparatus , ship navigate , communication , artificial intelligence , computer graphic , graphic management and so on . the function of route planning and advanced navigation in the system is based on electronic nautical chart . it bring forward the grid model in route planning , during the course of route planning , it provide ways to settle all kinds of instance ; it figures out the best head bearing of the ship with the real time transfer data from navigation apparatus to the system , accomplish the advanced navigation function in ecdis
  该系统是在电子海图基础平台上来完成航线设计和最优航法功能的，提出了在电子海图中利用网格模型来进行航线设计的方法，在求取最优航线的过程中，全面综合地考虑了各种可能出现的情况，并逐一解决；最优航行方法中采用实时获取船舶导航仪器传入到系统中的数据，并根据这些数据进行计算，给出船舶当前最佳船艏向，实现基于电子海图显示与信息系统的最优航法。
