METHOD FOR AUTOMATIC CONTROL OF HEADING OF SHIP AND INTELLIGENT SYSTEM FOR REALISING SAID METHOD Russian patent published in 2014 - IPC B63H25/00 

FIELD: physics; control.

SUBSTANCE: group of inventions relates to a method for automatic control of heading of a ship and an intelligent system for automatic control of heading of a ship. The method involves using a neural network model of the control object as a model of the control object. In order to adjust fuzzy logic algorithm parameters to be adjusted, the method involves obtaining and identifying heading data of the ship and control data; determining criteria feature data of movement of the ship based on the identified heading data of the ship and control data using a database of the behaviour of the ship on the heading; selecting a neural network model of the control object based on the determined criteria feature data of movement of the ship; determining data of the fuzzy logic algorithm parameters to be adjusted in accordance with the selected neural network model of the control object. The intelligent system includes a fuzzy logic controller, an emulator for correcting control action, feedforward and feedback between the control object, the fuzzy logic controller and the emulator. The emulator is in form of a neural network emulator. The neural network emulator includes a neural network classifier, a neural network model unit of the control object and an optimisation unit. The neural network classifier includes a database of the behaviour of the ship on the heading.

EFFECT: high-speed control processes and efficiency of filtering random perturbations of the system.
