Ship thrust distribution system and thrust distribution method

Abstract

The invention relates to a ship thrust distribution system and a ship thrust distribution method. The ship thrust distribution system comprises a parameter setting module, a limiting factor selectionmodule, a mathematical model establishment module, an optimization algorithm selection module, a distribution scheme generation module, a data storage module and an analogue simulation module. The ship thrust distribution method comprises the steps of: S1, setting a layout and parameters of a propeller; S2, setting limiting factors; S3, establishing a thrust distribution mathematical model; S4, selecting an optimization algorithm; S5, generating a thrust distribution scheme according to the thrust distribution model and an optimization algorithm; and S6, generating a plurality of thrust distribution schemes by adjusting the parameters. According to the ship thrust distribution system and the ship thrust distribution method, various thrust distribution schemes for different ships can be completed only by setting various parameters, and the different thrust distribution schemes can be simulated at the same time, so that a large amount of time for compiling simulation programs and analyzing simulation data is saved, and meanwhile, a large amount of cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of ship dynamic positioning control, in particular to a ship thrust distribution system and a thrust distribution method. Background technique [0002] The dynamic positioning of a ship refers to the ability of a ship to use propellers to resist external environmental forces, so that the ship can maintain or return to a designated position. Thrust distribution, as a main part of the dynamic positioning system, can form reasonable and effective thrust commands from the received force and torque signals on the three degrees of freedom and distribute them to each propeller, so that each propeller can issue corresponding thrust. Make the ship maintain or return to the specified position and bearing. [0003] The design of the traditional thrust distribution method needs to be customized for a specific ship. It takes a long process from the beginning of the design to the complete realization. Once the relevant e...
