WebJun 11, 2024 · Thrust allocation is the problem of determining the thrust and the direction of each of the n thruster devices of a ship, given the desired forces and moment from the control law. The problem of singular configurations is pointed out and solved by using a modification of the singular-value decomposition. WebAbstract: 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.
