中文摘要：

建模是评估船舶操纵性和可控性的重要前提。基于自由自航船模试验的系统辨识方法是求取船舶操纵运动数学模型中的水动力系数的有效手段之一。文中提出了一种使用支持向量回归估计的船舶操纵运动响应模型辨识方法，该方法通过训练自由自航试验数据样本得到参数回归模型。辨识和仿真结果验证了文中所提出的方法的有效性。

英文摘要：

Modeling is a vital precondition to evaluate ship maneuvering performance and controllability.System identification based on free-running model tests is one of the methods to obtain the hydrodynamic coefficients in mathematical models of ship maneuvering motion. In this paper, an identification method for determining the response models of maneuvering motion by using support vector regression （SVR） is presented. The proposed method uses analytic parameter regression from training samples obtained in free-running models tests,The results of estimation and simulation demonstrate the validity of the identification algorithm for conventional surface ships.
