A Constrained Thrust Allocation Algorithm for Remotely Operated Vehicles
IFAC-PapersOnLine, 2018 Abstract In this paper, the constrained thrust allocation problem is studied and solved for the class of over-actuated Remotely Operated Vehicles. In detail, we find the solution of the thrust allocation when the thrusters are affected by possible faults and, simultaneously, taking into account the thrusters’ saturation limits.

Fuel Optimal Thrust Allocation In Dynamic Positioning [PDF]
IFAC Proceedings Volumes, 2013 This thesis gives a short introduction to the Dynamic Positioning(DP) domain and focuses on developing a fuel optimal thrust allocation algorithm for marine DP vessels with a diesel electric power plant. Obtained data is used to develop a static model for the fuel consumption of a diesel generator, as a function of its produced power.

Optimizing Fuel Consumption in Thrust Allocation for Marine Dynamic Positioning Systems [PDF]
IEEE Transactions on Automation Science and Engineering, 2022 In offshore maritime operations, automated systems capable to maintain the vessel’s position and heading using its own propellers and thrusters to compensate exogenous disturbances, like wind, waves and currents, are referred to as Marine Dynamic Positioning (DP) Systems.

Design and Implementation of Pseudo-Inverse Thrust Allocation Algorithm for Ship Dynamic Positioning
IEEE Access, 2020 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 full ...

WCA: A New Efficient Nonlinear Adaptive Control Allocation for Planar Hexacopters
IEEE Access, 2023 This paper presents an efficient control allocation (CA) strategy which significantly improves the flight performance of a planar hexacopter. This allocation maps the desired control vector composed of the thrust and torques in roll, pitch, and yaw axis,
