| 摘 要： | 运用海浪谱分析方法,基于MATLAB/SIMULINK对航行中船舶遭遇到的海浪进行实时仿真,描绘出了不规则海浪的特征.海浪对船舶的控制和性能的研究带来很多不便,应该设法消除或削弱其影响.基于切比雪夫函数逼近方法, 设计了一种无限冲激响应(IIR)数字滤波器来实时地对海浪噪声进行滤波.对三级海况下船舶遭遇的海浪进行仿真实验,结果表明,该滤波器不仅设计简单、经济,而且实时性强,滤波效果显著.

| Abstract: | According to wave spectrum analysis theory, a real - time simulation of the waves encountered by a sailing vessel is carried out with MATLAB/SIMULINK, which describes the feature of the irregular waves. Lots of inconveniences are brought to vessel control and performance research by waves, which should be canceled or reduced with some measures. An Infinite Impulse Response (IIR) digital filter is designed easily and economically based on Chebyshev function to filter the wave disturbance real time. We applied it to the encountered wave at the third sea code and obtain perfect filtering effect with strong real - time ability. |
