船舶航行时,受到风浪影响产生的横摇运动会使船体摇晃。当倾斜角偏大,对于船体稳定性和安全性影响较大。减摇鳍控制技术上传统PID不具备自整定的能力,缺乏在不同海况下的适应性及调节能力,减摇作用与控制效果较差。将模糊控制与PID相结合,同时引入免疫调节,优化PID控制参数,免疫控制能形成有效的反馈,结合模糊和免疫二者优点,设计减摇鳍模糊免疫控制系统,并在Matlab中进行了仿真。结果表明,fuzzy-immune对海浪影响下的船舶横摇有很好减摇控制效果。
When the ship is sailing, the rolling motion caused by the wind and waves will shake the hull. When the inclination angle is too large, it will have a great impact on the stability and safety of the hull. In the fin stabilizer control technology, the traditional PID does not have the ability of self-tuning, lacks the adaptability and adjustment ability under different sea conditions, and the anti-rolling effect and control effect are poor. Combining fuzzy control with PID, introducing immune regulation, optimizing PID control parameters, immune control can form effective feedback, combined with the advantages of both fuzzy and immune, the fuzzy control system of fin stabilizer is designed and implemented in Matlab. The results show that fuzzy-immune has a good anti-rolling control effect on the ship rolling under the influence of the waves.
