AUTOMATIC RESET OF KINETIC ENERGY IN CASE OF INEVITABLE COLLISION OF SHIPS

Abstract

Considered issues of automatic reset of kinetic energy along the gradient in case of inevitable collision of ships. The target function of the fastest reset of kinetic energy is formed in the form of a scalar product of the gradient vector at the location of the vessel and the vector of the right parts of the mathematical model of the longitudinal and angular movement channels containing control. To form optimal controls, a nonlinear optimization procedure was used, taking into account control restrictions. The own ship's movement parameters (speed and course) used in the optimization procedure are measured by speed and course sensors, and the target's movement parameters are estimated from the measured values of the own ship's speed and course and the measured relative movement parameters using radar. The workability method was verified by mathematical modeling in a closed circuit with a control object. The results of the simulation showed that the automatic module provides a 9-fold reduction in the kinetic energy of the collision. The use of the automatic kinetic energy reset module in the event of an imminent collision will reduce the influence of the negative impact of decisions when handling a vessel under the influence of stress, reduce crew fatigue, prevent damage or even loss of the vessel and cargo, and save human lives.
