Perera, L.P., Oliveira, P. and Guedes Soares, C. (2011), “Dynamic Parameter Estimation of a Nonlinear Vessel Steering Model of Ocean Navigation”, Proceedings of the ASME 2011 30th International Conference on Ocean, Offshore and Arctic Engineering, OMAE2011, June 19-24, 2011, Rotterdam, The Netherlands, OMAE2011-50249, pp. 881-888

In this paper the stochastic parameters describing the nonlinear ocean vessel steering model are identified, resorting to an Extended Kalman Filter. The proposed method is applied to a second order modified Nomoto model for the vessel navigation that is derived from first physics principles. The results obtained resorting to a realistic numerical simulator for the nonlinear vessel steering model considered are illustrated in this study.
