摘　　要：为提高动力定位测量装置的准确性和精度,本文基于多传感信息融合技术进行船舶动力定位控制系统设计与仿真研究。在地球中心固定坐标系与北东地坐标系中,建立船舶动力定位系统传感测量模型,利用半实物仿真系统的试验数据,对建立的多传感信息船舶动力控制系统进行仿真分析。仿真结果表明,上述动力定位系统模型和控制系统结构能够满足船舶半实物仿真实验系统的电罗经测量数据的融合要求,且本文设计的船舶多传感信息融合方法的融合性能优于测量数据滤波后加权融合。本文研究结果可为船舶动力定位控制系统的设计与仿真提供理论指导和试验依据。To raise the accuracy of the measure equipment of dynamic positioning system,this paper present a design and simulation method for dynamic positioning system of vessels based on multisensor information fusion. In coordinate systems of conventional terrestrial pole and north east down,a sensor measurement model of dynamic positioning system was established. Semi- physical simulation systems is used to produce experiment information to simulate and analysis the established multi-sensor information fusion dynamic positioning control system. The simulation result shows that the dynamic positioning system model and control system are satisfied with the information measured by electric gyrocompass of dynamic positioning system. Fusion performance of the established multi-sensor information fusion method is better than the weighted fusion of the information after filtering. The research result of this paper can provide theoretical guidance and experimental basis for dynamic positioning control system of vessels.
