侧推器及其控制系统的研究与仿真

Research and simulation of thruster and its control system

大型船舶在航道或者港口中运动时,由于吃水深度和运动空间的限制,船体的操纵性比较差,也容易出现船舶碰撞、搁浅等事故,可调距侧推器是目前大型船舶常用的一种辅助推进方式,它能够在较狭窄的空间中为船舶运动提供侧向推力,提高船舶的运动性能。本文研究船舶侧推器及其控制系统的原理和仿真,从流体动力学方面建立侧推器的模型,分析了侧推器控制系统的构成,并基于Matlab软件平台进行了船舶侧推器控制系统的仿真验证,有助于提高大型船舶侧推器的设计水平。

When large ships move in the channel or port,due to the limitation of draft and moving space,the maneuverability of the hull is relatively poor,and ships are prone to collision,grounding and other accidents.At present,adjustable distance thruster is a commonly used auxiliary propulsion method for large ships,which can provide lateral thrust for ship movement in a narrow space and improve the motion performance of ships.The research direction of this paper is the principle research and Simulation of the ship thruster and its control system.The model of the thruster is established from the aspect of fluid dynamics,the composition of the thruster control system is analyzed,and the simulation verification of the ship thruster control system is carried out based on the Matlab software platform,which is helpful to improve the design level of the large-scale ship thruster.
