Parameters Estimation of Nonlinear Manoeuvring Model for Marine Surface Ship Based on PMM Tests
A nonlinear manoeuvring mathematical model of marine surface ship model is briefly introduced. In order to obtain the hydrodynamic coefficients, system identification is used to estimate the parameters using Planar Motion Mechanism (PMM) test data. Usually, the obtained parameters using measured dat...
