摘　　要：船舶动力定位系统(Dynamic Positioning System,DPS)主要由测量子系统、控制子系统和推进子系统组成。本文在前期研究基础上,结合推进器速度跟踪控制方法,采用发电机+可调负载的模式模拟未知海况下变化的负载,研发了C#和调速系统的通信接口,同时采用转速传感器反馈推进器的实际转速并在软件界面上显示。通过研发实际的半实物模拟系统,实验数据表明,在负载扰动下,模拟系统能够有效地跟踪推力分配发出的速度指令信号。The dynamic positioning system(DPS)consists of control subsystem,thrust allocation subsystem and measurement subsystem.Based on our previous research and combining the thruster speed tracking control method,the generator&adjustable load is employed to simulate the unknown oceanic environment to develop the communication interface between previous C#and speed regulation system.Furthermore,the actual speed of thruster is obtained via a speed sensor and is displayed in software interface.Experimental results show that the speed command signals can be tracked effectively via developed semi-physical simulation system.
