中文摘要：
基于自航模试验的系统辨识方法是一种有效的船舶操纵运动建模方法。通过对舵角和转艏角速度试验数据的分析，用岭回归方法确定了船舶操纵运动数学模型中的模型参数．进行了操纵运动预报仿真并同自航模试验数据对比，数值仿真结果验证了方法的有效性。
英文摘要：
System identification combined with free-running model tests is an effective method to the modeling of ship manoeuvring motion. By analyzing the test data of rudder angles and yaw rates, a method based on ridge regression was proposed for determining the coefficients in the mathematical model of ship manoeuvring motion. Predictions of manoeuvring motion were presented by using the identified model and compared to the test results. The simulation results demonstrate the validity of the identification algorithm proposed.
