基于e-航海的船舶智能航行

针对e-航海背景下的船舶绿色、低碳航行问题,本文提出一种基于非线性反馈的闭环增益成形算法。首先阐述了e-航海技术与船舶智能航行之间的共性,以大连海事大学无人船艇“蓝信”号为船舶模型,在保持已有的闭环增益成形算法不变的基础上,引入正弦函数驱动的非线性反馈代替原有的误差线性反馈。仿真结果表明,基于非线性反馈的闭环增益成型算法控制器更加节能,符合e-航海的要求;闭环增益成形算法控制器设计简单,工程中易于实现。

Intelligent navigation of ships based on e-navigation

Aiming at the green and low-carbon navigation problems of ships under the e-navigation, a closed-loop gain forming algorithm based on nonlinear feedback is proposed in this paper. Firstly, the commonness between e-navigation technology and intelligent navigation of ships is expounded. Taking the unmanned ship "Lan Xin" of Dalian Maritime University as the ship model, the sinusoid-driven nonlinear feedback is introduced to replace the original linear error feedback on the basis of keeping the existing closed-loop gain forming algorithm unchanged. Simulation results show that the closed-loop gain forming algorithm controller based on nonlinear feedback is more energy efficient and meets the requirements of e-navigation. The closed-loop gain forming algorithm controller is simple to design and easy to implement in engineering.
