A Novel Thrust Allocation Method Based on Improved Genetic Algorithm

This paper addresses the problem of thrust allocation for Dynamic Positioning (DP) marine vessels. This improved Genetic Algorithm combining the traditional genetic algorithm (GA) and pseudo inverse is used to find the optimal direction of each propeller. Based on the solved optimal direction, the thrust of propeller is obtained by QP. Simulation results show that the novel thrust allocation method has better global search performance and faster convergence speed than traditional GA and QP method.
