耙吸挖泥船航迹控制策略分析

摘要

随着船舶动力定位技术日趋完善,耙吸挖泥船DP/DT(Dynamic Positioning/Tracking)系统的使用大大提高了疏浚作业效率.DP/DT系统包括DP和DT两大功能,耙吸挖泥船以DT功能(动态寻迹)为主要特点.本文以耙吸挖泥船为背景,采用一种“视线”航迹控制策略,对其疏浚过程进行分析,并通过设计航迹控制器来验证该策略的可行性,同时运用VC++编程来显示实际航迹控制效果.%Recent years, with the development of dynamic positioning technology, DP/DT system for TSHD has been improved the efficiency of dredging. The system contains two main functions Dynamic Positioning and Dynamic Tracking, Dynamic Tracking is the main character for TSHD. This thesis introduces a control strategy LOS in order to improve the dredging efficiency, and designs the corresponding controller to validate the strategy. Also used the VC++ program language combined sea trials to display the actual control effect.
