DOI: 10.1016/j.ast.2021.106971
Abstract: Abstract Control allocation for 6-dof spacecraft maneuvers is considered. Retired spacecraft, whose own control system is inoperable, can be reused by installing multiple cellular thruster modules to provide thrusts for translational and rotational control. Such… read more here.

DOI: 10.1109/access.2019.2923718
Abstract: The pseudo-inverse method cannot optimize the angle and needs to give the azimuth angle artificially, therefore, when the dynamic positioning system has variable vector propellers and rudders, the pseudo-inverse method cannot be applied to the… read more here.
