Internal Model Control-Based Observer for the Sideslip Angle of an Unmanned Surface Vehicle

Journal of Marine Science and Engineering, 2022
Since the sideslip angle is often ignored or simplified in the process of path following of unmanned surface vehicle by using the line-of-sight (LOS) guidance law because of its fast change and the difficulty of measurement, an observer was proposed by ...

Linear determinantal equations for all projective schemes [PDF]

, 2011
We prove that every projective embedding of a connected scheme determined by the complete linear series of a sufficiently ample line bundle is defined by the 2-minors of a 1-generic matrix of linear forms.

IR sensor for line following robot [PDF]

, 2016
Generally, in a line following robot as shown in Figure 1.1, IR sensor is used for the robot to detect the line either white or black. The line can either be black on a white surface and white on a black surface.

Vortex spectrum in superfluid turbulence: interpretation of a recent experiment

, 2007
We discuss a recent experiment in which the spectrum of the vortex line density fluctuations has been measured in superfluid turbulence. The observed frequency dependence of the spectrum, $f^{-5/3}$, disagrees with classical vorticity spectra if ...

Neural Network-Based Adaptive Sigmoid Circular Path-Following Control for Underactuated Unmanned Surface Vessels under Ocean Disturbances

Journal of Marine Science and Engineering, 2023
This study describes a circular curve path-following controller for an underactuated unmanned surface vessel (USV) experiencing unmodeled dynamics and external disturbances. Initially, a three degrees of freedom kinematic model of the USV is proposed for

A Unified Approach for Underwater Homing and Docking of over-Actuated AUV

Journal of Marine Science and Engineering, 2021
During the implementation of time-consuming tasks such as underwater observation or detection, AUV has to face a difficult and urgent problem that its working duration is greatly shortened by the limited energy stored in the battery device.

Adaptive Observer-Based Line-of-Sight Guidance Law for Path Following of Underactuated Unmanned Surface Vehicle With Sideslip Compensation

IEEE Access
In this paper, the path following problem of an underactuated unmanned surface vehicle (USV) in the presence of environmental disturbances is considered. To compensate for the sideslip induced by drift forces, an adaptive Kalman-like observer is proposed
