Abstract: Abstract: By applying the LSsupport vector regression to analyze the data of rudder angle and yaw rate obtained from the deformed zigzag test of freerunning model, the manoeuvrability indexes in the response models of ship manoeuvring motion were identified. The obtained response models were solved numerically by RungeKutta method to simulate the deformed zigzag 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
