摘要： 通过对自航模变形Z形试验舵角与转艏角速度数据的分析，应用最小二乘支持向量回归机（Least SquareSupport Vector Regression，LSSVR）辨识了船舶操纵运动响应模型中的操纵性指数，并用回归得到的响应模型进行了变形Z形试验的数值模拟.通过将首向角和转艏角速度的预报结果与自航模试验数据进行比较，结果验证了该方法的有效性.

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
