摘　　要：根据船舶动力定位系统的工作原理,基于MATLAB语言将环境载荷计算、推力计算、推力分配、图形绘制等功能进行集成,完成动力定位能力频域分析模块开发,并结合Kalman滤波算法采用LQR方法进行反馈控制,完成时域分析模块开发。以某型海洋调查船为算例,利用该程序绘制了动力定位能力曲线,并且与Kongsberg Maritime分析报告进行对比,结果吻合良好,为推进器的选型与布置提供了依据;进行时域模拟给出海洋调查船的位置、姿态的时历曲线和各个推进器的推力响应情况,为实际工程提供了指导。In this paper, according to the principle of Ship Dynamic Positioning System, the function of the environment load calculation, thrust calculation, thrust distribution and graphics rendering are integrated based on MATLAB language that completed dynamic positioning capability frequency domain analysis module development; and then combining with Kalman filter algorithm and using LQR method for feedback control, completed time domain analysis module development. Taking a type of marine survey ship for example, firstly, the program is used to draws the dynamic positioning capability curve, and compared with the results of Kongsberg Maritime report, the results are in good agreement to provide evidence for improving the selection and arrangement; Then the time domain simulation, gives the oceanographic ship＇s curve of position and posture and the response curve of the all propeller, provided guidance for the actual project.
