Abstract

The invention discloses a ship automatic berthing nonlinear neural network control method. The method comprises the following steps: performing a large amount of successful berthing by utilizing ship,acquiring training data, designing a controller by utilizing three-layers of nonlinear neural network, and training network weight and deviation by utilizing a BP algorithm; and realizing the outputof the ship automatic berthing control under different initial input conditions by utilizing a generalization performance of the ANN. The remote monitoring and control of the unmanned ship can be realized through the technical scheme provided by the invention; the provided automatic berthing control method is independent of a virtual navigation route with uncertain element; in the actual control process, the computation load is reduced, an ideal control effect is reached when the control instantaneity is improved, and the voyage practice requirement is satisfied.

Description

technical field [0001] The invention relates to the technical field of unmanned ship control, in particular to a control method and system for automatic berthing of ships by using big data on ship navigation. Background technique [0002] With the rapid development of robot technology, modern communication technology, computer technology, data mining technology and navigation technology, unmanned ship technology is gradually applied to sea surface environment monitoring, marine meteorological forecast, communication relay, maritime accident search and rescue, maritime traffic guidance, Assist in the maintenance of maritime traffic order, near- and long-range target recognition and tracking, and automatic driving of unmanned commercial ships. At present, the operation methods of unmanned ships are mainly divided into two forms: fully automatic operation and manual remote control operation, or manual control and autonomous navigation dual-mode control. [0003] With the devel...
