摘　　要：随着深海技术的不断发展,动力定位系统的在海洋工程上得到广泛应用。动力定位系统通过其控制系统驱动船舶推进器来抵消风、浪、流等作用于船上的环境外力,从而使船舶保持在确定的位置上或沿预期的航迹航行。本文在分析了国际海事组织和国际海洋工程承包商协会对动力定位系统定义及分级要求的基础上,阐述了国外船舶动力定位系统的发展及其应用状况,分析了动力定位系统的组成和工作原理,研究了动力定位系统的各种约束、控制策略、控制技术、推力分配等关键技术,指出动力定位系统精度取决于控制系统和测量系统性能,并提出了发展国产动力定位系统应采用的途径。With the developments of deep-sea technologies, the dynamic positioning system（DPS） has been widely applied in offshore project. The dynamically positioned system of a vessel is designed to accurately maintain the vessel＇s position and heading at a fixed location or a predetermined track for marine operation purposes by exclusively using active thrusters. In this paper, the development and application of the dynamic positioning（DP） system were investigated. The principle how the DP works was analyzed. The typical configurations of the foreign famous DPS were studied. The system restrictions, control strategy, control technology, and thrust allocation of DP were analyzed. It was pointed that the accuracy of dynamic positioning system depends on dynamic positioning control and measurement equipment. Based on the researches above, an approach to develop our own dynamic positioning system was presented.
