| 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: | 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. |
