Abstract Abstract： By applying the LSsupport vector regression to analyze the data of rudder angle and yaw rate obtained from the deformed zigzag test of freerunning model, the manoeuvrability indexes in the response models of ship manoeuvring motion were identified. The obtained response models were solved numerically by RungeKutta method to simulate the deformed zigzag manoeuvres. The prediction results of heading angle and yaw rate were compared with the test data to verify the proposed method.
Key words： ship manoeuvring; response model; parameter identification; support vector regression
