基于动力定位应用的直翼桨模拟器开发

Development of VSP Simulator Based on Dynamic Positioning Application

直翼桨能够在不改变转速的情况下实现推力大小和方向无极可调,因而被广泛应用于高动力定位控制要求的场合。然而配套的直翼桨装置往往都是引进设备,供货周期长,因此在船舶设计阶段,一般并不具备动力定位控制装置与直翼桨实物联调的条件。直翼桨模拟器的开发可弥补这一缺陷。文章以直翼桨水动力性能研究为基础,通过映射关系实现推力矢量与控制点信息之间的解算,模拟直翼桨的工作性能,从而为接口调试、协同控制算法验证及优化设计提供条件。

Voith-schneider Propeller(VSP)is widely used in the application for the high dynamic positioning(DP)control because it can implement the stepless adjustment of the magnitude and direction of the thrust without changing the revolution.However,it is impossible for the debug between the DP control system and the VSP in the design stage because the VSP is often imported with a long delivery period.The development of VSP simulator can fi ll this gap.The relationship between the thrust vector and the control point information can be calculated and solved by using the mapping method based on the research of the hydrodynamic performance of the VSP.The working performance of the VSP is simulated to provide the conditions for the interface test,the collaborative control algorithm verifi cation and the optimization design.
