摘要:

为了实现海洋石油支持船动力定位模块中的推力分配子功能，提出在现有航海模拟器的基础上升级添加动力定位模拟器模块，研究其中的推力分配方法及实现。利用伪逆法进行推力分配，采用动态链接库技术完成Matlab仿真代码转化，联合QT界面形式完成软件功能模块设计，通过软件实时对控制力向量进行推力分配计算并显示。研究结果表明，该推力分配子功能模块能够有效并快速进行推力分配计算，可以作为子功能集成于现有航海模拟器中。

Abstract:

In order to realize the thrust distribution sub-function in the dynamic positioning module of the offshore oil support ship, the dynamic positioning simulator module was upgraded and added on the basis of the existing navigation simulator, and the thrust distribution method and implementation were studied. The pseudo-inverse method was used for thrust allocation. The dynamic link library technology was used to complete the Matlab simulation code conversion. The software function module design was completed in the form of joint Matlab and QT interface. The thrust allocation was calculated and displayed by the software in real time. The results show that the thrust allocation sub-function module developed in this paper can effectively and quickly perform thrust allocation calculation, and can be effectively integrated as a sub-function in the existing navigation simulator.
