NONLINEAR ADAPTIVE HEADING CONTROL FOR AN UNDERACTUATED SURFACE VESSEL WITH CONSTRAINED INPUT AND SIDESLIP ANGLE COMPENSATION

open access: yesBrodogradnja, 2020
In this paper, a nonlinear adaptive heading controller is developed for an underactuated surface vessel with constrained input and sideslip angle compensation. The controller design is accomplished in a framework of backstepping technique.

Soft-Switching Proximate Time Optimal Heading Control for Underactuated Autonomous Underwater Vehicle

open access: yesIEEE Access, 2019
In this paper, a soft-switching proximate time-optimal control (PTOC) is proposed based on the model-compensation extended state observer (ESO) and Takagi-Sugeno fuzzy switching, for the fast set-heading tracking of underactuated autonomous underwater ...

Head Module Control of Mediator Interactions [PDF]

open access: yesMolecular Cell, 2006
Yeast Mediator proteins interacting with Med17(Srb4) have been expressed at a high level with the use of recombinant baculoviruses and recovered in homogeneous form as a seven subunit, 223 kDa complex. Electron microscopy and single-particle analysis identify this complex as the Mediator head module.

Surface ship heading control with sideslip angle and input saturation

open access: yesZhongguo Jianchuan Yanjiu, 2021
ObjectivesTo address the impact of non-zero sideslip angle and input saturation on the heading control of a surface ship, a method based on a backstepping control algorithm is proposed.Methods The actual sideslip angle is obtained through the relative ...

Dynamic control of head mesoderm patterning [PDF]

open access: yesDevelopment, 2011
The embryonic head mesoderm gives rise to cranial muscle and contributes to the skull and heart. Prior to differentiation, the tissue is regionalised by the means of molecular markers. We show that this pattern is established in three discrete phases, all depending on extrinsic cues.

Translational control from head to tail [PDF]

open access: yesCurrent Opinion in Cell Biology, 2009
mRNA translation, a highly coordinated affair involving many proteins and RNAs, is generally divided into three steps: initiation, elongation, and termination. Each of these steps serves as a point of regulation to control the amount of protein that is produced.

Design of submarine heading sliding mode controller based on NESO

open access: yesZhongguo Jianchuan Yanjiu, 2018
[Objectives] To realize submarine steering control with low noise when a submarine sails on a surface in a complex sea state, [Methods] a heading controller is designed based on linear motion model on horizontal plane.

Head Controlled Mouse

open access: yesInternational Journal of Computer Applications, 2012
The basic idea of the projects is to build a human machine interface which can be used to control mouse using head-tilt and eye-blink. This mouse-emulating device can be found to be most useful by physically handicapped people who can no longer control the computers using their hands.

Numerical Study on Characteristics and Control of Heading Angle of Floating LNG Bunkering Terminal for Improvement of Loading and Off-loading Performance

open access: yes한국해양공학회지, 2020
In this study, heading characteristics and heading control performances were evaluated to achieve the wave shield effect. The wave shield effect originating from heading control reduces the relative motions of moored vessels in a floating liquefied ...
