为快速构建符合海洋航行器实际运动特性的操纵运动模型,开展基于"精海"无人艇实航湖试数据驱动的无人艇操纵运动辨识建模研究.无人艇操纵运动辨识建模的框架以非线性水动力模型和推进器经验模型作为先验知识约束,利用随机舵角序列激励下的航行数据作为训练集,采用支持向量机回归方法完成建模过程,着重探讨了在环境干扰下构建艇体动力学模型的可行性.结果表明,所提出的方法能够快速构建具有非线性特性的无人艇操纵运动模型;先验的模型结构有效降低了实航数据中浪和流的影响,构建的模型能够有效预测回转、Z形等操纵运动的状态变化,具有良好的泛化能力.
Data-Driven Modeling of Unmanned Surface Vehicle's Maneuvering Motion Based on Real Navigational Data
This study conducts a data-driven modeling research of the"Jinghai"unmanned surface vehicle based on lake trial data.The objective is to develop a kinetic model that captures the actual characteristics of the vehicle.The framework incorporates the nonlinear hydrodynamic model structure and the model of the propulsion system as prior knowledge constraints.Support vector regression is employed to complete the modeling process using a training dataset excited by a sequence of random rudder angles.The study places a particular emphasis on assessing the feasibility of modeling with environmental disturbances.The results demonstrate that the proposed method enables rapid construction of a nonlinear model for unmanned surface vehicles.The prior model structure effectively mitigates the impact of waves and currents in navigational data.The model accurately predicts the motion states during turning and zigzag trials,and exhibits good generalization ability.
