In order to adapt to marine operations and improve the positioning accuracy of ships, this paper proposes an improved marine predator's algorithm for ship power system thrust distribution. An objective function for minimizing the power loss of the propulsion system is established. The function is constrained by the angle, magnitude and rate of change of the thrust direction. To solve the problem that the conventional Marine Predator's Algorithm (MPA) easily falls into local optimum, an adaptive t-distribution change operator is introduced to update the population to avoid falling into local optimum. The updated populations are grouped and learned according to the fitness to further improve the population quality and search accuracy. The traditional marine predator's algorithm is also compared with the improved simulation results, and it is concluded that the improved algorithm can deliver the commands of the power positioning system controller more accurately under the environmental disturbance and effectively reduce the power loss when the ship is sailing.
