现有的航向航迹自动舵检测平台使用了航迹自动舵标准（IEC62065）中提出的船舶运动模型，该模型对螺旋桨推进力、流体阻力等物理量进行了简化处理，对于非典型船的仿真精度不够，在实际使用中具有一定局限性。本文利用已具有相当精度的船舶四自由度MMG模型进行试验，提出通过设计MMG模型仿真试验求取IEC62065模型中相应参数值的方法，完成MMG模型向IEC62065模型的转化。仿真试验结果表明，采用该转化方法得到的IEC62065模型与原模型拟合度较高，获得了较好的模型转化效果。
There are limitations of the ship model proposed by IEC62065 which is commonly used in existing detection platform of autopilot because the simplified physical parameters of propeller propulsion, fluid resistance and so on. Based on the stimulation experiment of four degree MMG model with considerable accuracy for ships, this paper complete the transformation from the MMG model to the IEC62065 model, using the method of obtaining the corresponding parameter values in the IEC62065 model by designing the MMG model simulation experiment. The simulation experiment proves the high fitting degree between the IEC62065 model and the MMG model by using this method. And a good model transformation effect is obtained.
