摘　　要：根据运动特性建立耙吸挖泥船的数学模型,将Kalman滤波技术应用于耙吸挖泥船动力定位系统,并进行Matlab仿真。仿真结果表明,Kalman滤波器具有很好的滤波效果,在环境力的影响下,能够得到理想的船位和艏向,是动力定位的有效方法。Based on the characteristics of the ship motion,the mathematical model of the trailing suction hopper dredger was built.The Kalman filter technology was applied in the dynamic positioning system（DPS） for the trailing suction hopper dredger and simulated it by Matlab.The results indicated that the Kalman filter can substantially provide the ideal motion and heading even in severe environmental conditionings.It′s an effective way of dynamic positioning.
