In order to develop the full-featured dynamic positioning simulator with good extensibility, the function of each module of DP system is analyzed. System architecture is designed and improved based on the existing navigation simulator. According to the principle of auto position mode, DP controller and thruster allocation algorithm are designed. Human-machine interface module is developed by using Direct2D graphics technology. Under the architecture of DP simulator, the simulation experiments verify the effectiveness of the proposed algorithm, which can simulate Auto Position and system information display.%为了自主研发功能完备、扩展性好的船舶动力定位模拟器，分析船舶动力定位模拟器中各个模块的功能，对现有航海模拟器的系统架构进行改进，提出适用于多单元协同仿真的船舶动力定位模拟器系统架构。根据动力定位系统自动定位模式的原理，设计动力定位控制器和推力分配算法，提出使用 Direct2D图形技术来设计动力定位人机交互界面。最后在所设计的动力定位模拟器系统架构下，以1艘动力定位供给船为仿真对象实现在不同海况条件下的自动定位功能和系统信息显示，并验证算法的有效性。
