摘要
海浪干扰对船舶的航向输出具有很大的影响,而运用海浪滤波器可以有效地消除海浪干扰,提高船舶的 控制品质。本文系统地研究了H∞滤波技术及其在海浪干扰处理中的应用,设计出了具有较强鲁棒性的海浪 干扰滤波器,并通过MATLAB软件中的仿真工具Simulink对该滤波器进行了仿真研究。通过分析仿真结果 可知,H∞滤波器的滤波效果比较稳定,估计精度较高。能够有效地减小打舵的幅值和次数,达到节能的目的。 总的来说,设计的H∞海浪滤波器能够有效地消除海浪干扰,并具有较强的鲁棒性。
The heading angle of ship is significantly affected by wave disturbance. The application of wave filter will be able to reduce the high frequency effect of the wave disturbance effectively and improve the control performance remarkably. H∞ filtering technology and its application to the design of wave filter for ships are systemically investigated in this paper. H∞wave filter with better robustness is designed and simulation study is conducted using Simulink. The analysis of the simulation results indicates that the filtering effect is more stable, the estimation precision is higher, and energy is saved by the reduction in rudder amplitude and rudder rate. H∞ wave filter designed in this paper can effectively filter wave disturbance and has stronger robustness. .
