Dual-Quaternion Analytic LQR Control Design for Spacecraft Proximity Operations [PDF]

open access: goldSensors, 2021
Proximity operations offer aggregate capability for a spacecraft operating in close proximity to another spacecraft, to perform on-orbit satellite servicing, or to a space object to perform debris removal. To utilize a spacecraft performing such advanced

Dual Quaternion Functions and Its Applications [PDF]

open access: goldJournal of Applied Mathematics, 2013
A dual quaternion is associated with two quaternions that have basis elements e0, e1, e2, e3, and ε. Dual numbers are often written in the form z=ζ+εζ*, where ε is the dual identity and has the properties ε2=0  (ε≠0).

On Rayleigh Quotient Iteration for the Dual Quaternion Hermitian Eigenvalue Problem [PDF]

open access: goldMathematics
The application of eigenvalue theory to dual quaternion Hermitian matrices holds significance in the realm of multi-agent formation control. In this paper, we study the use of Rayleigh quotient iteration (RQI) for solving the right eigenpairs of dual ...

Analytical dual quaternion algorithm of the weighted three-dimensional coordinate transformation [PDF]

open access: goldEarth, Planets and Space, 2022
Considering that a unit dual quaternion can describe elegantly the rigid transformation including rotation and translation, the point-wise weighted 3D coordinate transformation using a unit dual quaternion is formulated.

Dual Quaternion Visual Servo Control. [PDF]

open access: yesProc IEEE Conf Decis Control, 2020
This paper focuses on a dual quaternion-based estimation and control approach for position-based visual servoing (PBVS). The pose estimation of the camera is achieved using a dual quaternion-based Extended Kalman Filter (EKF), which estimates the position and orientation of the camera based on feature points acquired through a sequence of camera images.

A dual quaternion algorithm of the Helmert transformation problem [PDF]

open access: goldEarth, Planets and Space, 2018
Rigid transformation including rotation and translation can be elegantly represented by a unit dual quaternion. Thus, a non-differential model of the Helmert transformation (3D seven-parameter similarity transformation) is established based on unit dual ...

Fixed-time regulation of spacecraft orbit and attitude coordination with optimal actuation allocation using dual quaternion [PDF]

open access: yesFrontiers in Robotics and AI, 2023
On-orbit service spacecraft with redundant actuators need to overcome orbital and attitude coupling when performing proximity maneuvers. In addition, transient/steady-state performance is required to fulfill the user-defined requirements.

Dual third-order Jacobsthal quaternions [PDF]

open access: diamondProyecciones (Antofagasta), 2018
In 2016, Yüce and Torunbalcı Aydın (18) defined dual Fibonacci quaternions. In this paper, we defined the dual third-order Jacobsthal quaternions and dual third-order Jacobsthal-Lucas quaternions. Also, we investigated the relations between the dual third-order Jacobsthal quaternions and third-order Jacobsthal numbers.
