中文摘要：
为了获得形式简洁而精度较高的船舶运动数学模型,将航空航天领域的特征模型移植到航海领域。利用部分实船试验数据辨识出特征模型的参数,通过船舶Z形试验验证了在航海领域使用特征模型的可行性。该精度稍高于目前使用的Nomoto模型,且保留了其简洁的形式。
英文摘要：
In order to set up a new ship motion mathematical model that is simple in forms and has higher precision,a characteristic model applied in the fields of astronautics and aeronautics is introduced into the field of marine navigation.Parameters of the characteristic model are identified from real ship test data,and the feasibility of applying the characteristic model in marine navigation field are validated with ship zig-zag tests.Comparative results show that the characteristic model is simple and has slightly higher precision than that of the Nomoto model.
