| dc.description.abstract | The purpose of the study is to reduce dynamic positioning deviations of the offshore vessel with two stern azipods and a bow thruster. The following methods were used in the study: linear algebra, to finding the determinant of the actuators redundant structure minors, singular states of the structure and states maximally distant from singularities; conditional optimization, to determine the optimal states of the structure with the maximum determinant; mathematical modeling, to verify the operability and effectiveness of the developed model. A process mathematical model for adjusting the redundant structure has been developed, which allows, during dynamic positioning operations, to reduce dynamic deviations and increase accuracy. The obtained result is explained by: using the on-board controller in the control system, finding, at each step of the on-board controller, the optimal state of the structure, determined by the maximum determinant, by solving the conditional optimization problem, taking into account the constraints of the equalities type (for simultaneous formation of the necessary controls), and the inequalities type (for taking into account the physical constraints of the structure on the thrust force and the propellers rotation angles); reconfiguring the structure to a certain optimal position. | |
