Thrust allocation under ship failure based on improved Drosophila algorithm

Large-scale power positioning ships often encounter propeller failure problems when sailing over long distances, which brings danger to navigation. In order to solve the problem of propeller failure of power positioning ships, this paper proposes an improved Drosophila optimization algorithm to allocate the thrust force when the ship’s propeller fails. The experimental results show that the improved Drosophila optimization algorithm can still allocate the thrust and torque stably after the ship’s failure, so that the ship can sail from the expected position to the desired position and complete the power positioning function.
