Abstract :
This documentation presents the parametric identification of Nomoto models by using the proposed integral sample structure for identification (ISSI). The dataset used for validations are obtained from the free-running model tests. By analyzing the experimental data including yaw rate and rudder angle, the maneuvering indices in the 1st-order linear and nonlinear Nomoto models are approximated based on least square support vector machines (LS-SVM), where ISSI and the conventional Euler sample structure for identification (ESSI) are employed for the construction of the in-out sample pairs, respectively. The comparison between ISSI and ESSI is carried out for the validation of the proposed sample structure for identification.
