Abstract:
Stormy sailing conditions are among the most extreme and dangerous. The rocking of the ship in the roll
and trim channels greatly exhausts the crew, which leads to an increase in the number of errors when
making management decisions. The situation worsens also due to the fact that during a storm such
dangerous phenomena as harmonic and parametric resonances, a decrease in stability on passing waves,
broaching, impacts of group waves in the stern, which can lead to the , hull destruction,
overloads of the power plant and occurrence of blackouts. The most radical way to combat such dangers
is the automation of control processes. The authors have developed a method of automatic and optimal
control of the ship's movement in storm conditions, which allows to avoid the occurrence and
development of dangerous phenomena that lead to the capsize of the ship. The obtained result is explained
by: the use of an on-board computer in the ship's motion control system; constant measurement of ship
movement parameters and waves; finding, at each step of the on-board computer, safe and optimal values
of the ship's course and speed by solving the optimization problem; taking into account when solving the
optimization problem linear and non-linear constraints of the type of inequalities that define dangerous
areas; maintaining safe and optimal movement parameters using the automatic control system. The
theoretical significance of the obtained result lies in the development of a method of automatic and optimal
control of the ship's movement in conditions of stormy sailing. The practical significance of the obtained
results consists in: verification of the developed method by mathematical modeling; the possibility of using
the method in the automatic control system, which allows to automate and optimize the processes of
controlling a ship in a storm, reduce the influence of the human factor on control processes, crew fatigue,
risks of losing the ship and cargo, and generally increase the safety of shipping
