摘要: 基于船舶自动识别系统(AIS)数据提出一种船舶操纵性指数的辨识模型。通过对船舶AIS数据进行处理和解码,运用三次样条插值法对ROT值进行数据重构。通过时间序列的频谱分析法筛选合适的ROT值航段,通过船载航行数据记录仪(VDR)获得船舶在选定ROT值航段的舵角信息。运用粒子群优化算法(PSO)对处理后的AIS数据进行参数辨识,得到船舶在当前速度下的船舶操纵性指数值。通过与船舶真实操纵性指数值进行Z型仿真试验和旋回仿真试验对比,结果表明,应用粒子群优化算法可以实现基于AIS数据的船舶操纵性指数的辨识。

Abstract: A novel method of ship maneuverability index identification on the basis of Automatic Identification System (AIS) data was proposed. By decoding and processing the raw data of AIS, data of rate of turning (ROT) are re-constructed with application of cubic spline interpolation method. Time series spectrum analysis was introduced to select appropriate ROT data segment. Based on the ROT data segment, rudder angle information was obtained by using ship Voyage Data Recorder (VDR). To identify ship's maneuverability index, particle swarm optimization algorithm (PSO) was applied to obtain ship maneuvering parameters under the current speed. The result was compared with actual ship maneuvering index estimated by zigzag simulation experiment and cycle simulation experiment, which indicates that PSO can be introduced to identify ship maneuverability index.
