| 摘 要： | 作者设计并制作了伪随机二进制(PRBS)信号发生器。并以PRBS信号操舵,辨识了船舶操纵运动方程的系数。用离散时间测量决定线性连续时间模型参数。给出了Mariner标准模型和一艘渔轮的辨识结果,并与标准的Nomoto K,T计算结果进行了比较,结果令人满意。

| Abstract: | This paper presents the system identification applied to the determination of ship dynamics.In this paper, the PRBS signals which are produced by PRBS signal generator made by ourselves are used in operating ships to identify the coefficients of ship manoeuvring equations. The parameters of a continuous time model are determined by using discrete time measurements. The identification results from a Mariner model and a fishing vessel show good agreement with those from the Nomoto's method. |
