Intelligent safe ship control methods in collision situations

The paper describes the application of selected methods of optimal control theory, game theory and artificial neural networks with the aim of computer support for safe ship steering. It shows the structure of the control system and defines the task of safe steering. Also presented are methodologies and models for collision avoidance strategies. Using Matlab/Simulink language - positional game, risk game and dynamic optimal trajectory programs have been developed to provide decision support for collision avoidance at sea. A computer simulation showing safe trajectory through twelve objects at sea illustrates this.
