摘要
动力定位是指船舶利用推进器和螺旋桨等产生作用力,在控制系统的指令下抵消海上干扰因素的作用力和力矩,使船舶或作业平台悬停在海域内某特定位置,在远洋勘测、海上补给等方面有重要的应用。模糊控制是一种有效的自适应控制技术,本文建立了船舶的运动学模型,并基于自适应模糊控制理论设计和开发了一种船舶动力定位试验平台,对试验平台的动力定位原理和结构进行详细介绍。本研究对改善船舶的动力定位系统,提高船舶的稳定性有重要价值。
Dynamic positioning refers to the propeller and propeller force by ship,maritime force and moment offset interference factors in the control system under the command of the ship or platform to hover over the waters to a specific location,has important applications in ocean exploration,marine supplies etc..Fuzzy control is an effective adaptive control technology,this paper has established 3 degrees of freedom kinematic model of the ship,and based on the adaptive fuzzy control theory to design and develop a test platform of ship dynamic positioning,dynamic positioning of the experimental platform of the principle and structure are introduced in detail.This study is of great value to improving the dynamic positioning system of the ship and improving the stability of the ship.
