摘　　要：以海洋船舶为被控对象,针对系统的非线性特性,为克服船舶物理模型精确物理参数不易获得等问题,故用统计建模的方法,采用RBF-ARX模型对船舶的航向保持非线性控制过程进行建模.并比较了船舶RBF-ARX模型、ARX模型和物理模型的长期预测输出,验证了RBF-ARX模型在对船舶航向保持控制系统建模中的有效性和优越性.Based on the nonlinear characteristic of the ship, it is difficult to obtain accurate physical parameters of the ship physical model. Therefore, the statistical modeling method and RBF-ARX model is used to model the ship course-keeping control process. In this paper, the RBF-ARX model, the ARX model and the long-term predictive output of the physical model are compared, and the effectiveness and superiority of the RBF-ARX model in the ship course-keeping control system modeling are verified.
