A Matlab toolbox for parametric identification of radiation-force models of ships and offshore structures

Abstract

This article describes a Matlab toolbox for parametric identification of fluid-memory models associated with the radiation forces ships and offshore structures. Radiation forces are a key component of force- to motion models used in simulators, motion control designs, and also for initial performance evaluation of wave-energy converters. The software described provides tools for preparing non -parmatric data and for identification with automatic model-order detection. The identification problem is considered in the frequency domain. © 2009 Norwegian Society of Automatic Control.
