Comparing generic and vectorial nonlinear manoeuvring models and parameter estimation using optimal truncated least square support vector machine
Xu, Haitong; Hassani, Vahid; Soares, C. Guedes (Journal article; Peer reviewed, 2020-04)An optimal truncated least square support vector machine (LS-SVM) is proposed for the parameter estimation of nonlinear manoeuvring models based on captive manoeuvring tests. Two classical nonlinear manoeuvring models, ... -
Real-Time Parameter Estimation of a Nonlinear Vessel Steering Model Using a Support Vector Machine
Xu, Haitong; Hinostroza, M. A.; Hassani, Vahid; Guedes Soares, C (Journal article; Peer reviewed, 2019-06-19)The least-square support vector machine (LS-SVM) is used to estimate the dynamic parameters of a nonlinear marine vessel steering model in real-time. First, maneuvering tests are carried out based on a scaled free-running ... -
Truncated least square support vector machine for parameter estimation of a nonlinear manoeuvring model based on PMM tests
Xu, Haitong; Hassani, Vahid; Guedes-Soares, C. (Journal article; Peer reviewed, 2020-04)A new version of least square support vector machine (LS-SVM), the truncated LS-SVM, is proposed to estimate the nondimensionalized hydrodynamic coefficients. Truncated LS-SVM is shown to be an efficient and robust method ... -
Uncertainty analysis of the hydrodynamic coefficients estimation of a nonlinear manoeuvring model based on planar motion mechanism tests
Xu, Haitong; Hassani, Vahid; Guedes Soares, Carlos (Journal article; Peer reviewed, 2019-02-01)Uncertainty analysis of the identified hydrodynamic coefficients of a nonlinear manoeuvring model is presented in this paper. The classical parameter estimation method, Least Square, is briefly introduced, and the uncertainty ...
