IDENTIFICATION OF PARAMETERS OF MATHEMATICAL NON-LINEAR MODEL OF VESSEL LONGITUDINAL MOTION

The article considers the important task of modern control theory to construct an adequate mathematical model a specific dynamic object or vessel movement, that is, its identifica-tion (structural parametric). It is proposed nonlinear longitudinal motion ship. Practical data were obtained experimentally, brief description experimental platform for unmanned boat and equipment used in study characteristics given. noted characterized by three modes movement: displacement, transitional planning. relationship between thrust propeller speed determined. To solve identification problem work, it use apparatus power series. series coefficients are determined experimentally. selecting can be solved using least squares method. In order avoid cumbersome calculations there numerical optimization methods applying capabilities MS Excel computing environment. solution was different number members (N = 1, 3, 5). efficiency approach justified.
