摘　　要：以耙吸挖泥船为应用背景,介绍了动力定位/动态跟踪的发展和现状,设计出基于模糊的PID控制算法来实现位置保持和按预定航迹疏浚。根据工程经验制定了符合耙吸挖泥船应用的模糊规则,同时通过Matlab及Simulink对其进行仿真。实验结果表明,该控制算法在环境力的影响下,DP/DT效果良好,满足工程实际需要。With the description of Dynamic Positioning and Dynamic Tracking （DP/DT）System for a Trailing Suction Hopper Dredger,the positioning and tracking under predefined circumstances is enhanced by fuzzy PID control algorithm. Based on the engineering experience,the rules of fuzzy-PID for Trailing Suction Hopper Dredger is customized and simulated by Matlab and Simulink. The tests show that the newly developed control algorithm substantially provides efficient DP/DT control performance even in severe environmental conditions and satisfies the practical requirements.
