Abstract

In this paper we presents a model of vessel motion control with the possibility to change the cargo mass. In the framework of the model we consider external forces acting on the vessel, the magnitude of which can be variable. We also present an analytical approach for analysis of the considered model. The approach gives a possibility to take into account changing of parameters of the in time, as well as the nonlinearity of the model.

Introduction

Vessel controllability is a topical issue to decrease quantity of accidents and optimizing cargo transportation. In this regard, a forecast of vessel movement is necessary. One of the classic methods for choosing a vessel's route is to calculate its possible trajectory depending on various parameters [1-5]. Another topical issue is increasing the buoyancy and stability of a vessel. In this paper we introduce a vessel movement model that is more general than those introduced in literature. We also presents an analytical approach to analyze the model.
