摘要
为提高船舶靠泊安全,对接智能靠泊,实现船舶抵泊过程中的姿态控制,运用切比雪夫拟合法、95%置信度区间法、最小二乘法及上述组合方法的2次拟合等优化策略,拟合区间化船舶自动识别系统(AIS)数据中速度、航向、艏向和船位等靠泊控制参数,构建区间化AIS数据驱动的多维抵泊姿态控制模型,并采用某轮靠泊南京龙潭港一年的AIS数据测试模型可靠性。研究结果表明:模型拟合方法优于现有拟合方法,且输出结果符合相关规则规定,所提出的模型满足抵泊过程船舶姿态安全控制要求。
In order to improve berthing safety and docking intelligent berthing,attitude control in the process of ship docking was realized,through using some optimization strategies such as Chebyshev fitting method,95% confidence interval method,least 2 method,two times fitting of above combination method and so on. Berthing control parameters,such as speed,heading,heading and ship position were fitted in the data of interval vessel AIS. A multi-dimensional attitude control model driven by interval AIS data was constructed,and reliability of model was tested by AIS data of a certain wheel berthing in Longtan Port,Nanjing for one year. The results show that model fitting method is superior to existing fitting method,and output results are in line with relevant rules,and proposed model meets requirements of ship attitude safety control during docking process.
