Optimal Thrust Allocation for Ship Dynamic Positioning System

摘要

The thrust allocation of a ship dynamic positioning system allocates the desired forces to thrusters by calculating thrust and angle of each thruster. Due to the problem of allocation failure arising from the thrust optimization allocation algorithm in the situation of the desired forces caused mutation, this paper puts forward the method based on the truncation of multiobjective optimization, which aims to maximize the ability of the propellers. The simulation results prove that the proposed method can effectively solve the problem.
