摘要
船舶在复杂水面环境中航行时,由于波浪对船体的扰动,船舶在航行时会发生纵横方向上的摇荡等各种运动,由于横摇受到风浪的作用最为明显,对船舶的整体稳定性影响也是最大的。为了有效改善船员在舱室里的生活环境,需要减摇鳍对船舶的摇摆进行抵消,降低其不稳定性。本文对船舶的零航速减揺鳍工作原理进行叙述,并分析其控制模型,通过改进的遗传算法,优化减揺鳍的控制器参数,同时设计虚拟的海洋运行环境,对减摇鳍的控制效果进行仿真,使减揺效果达到最优。
When a ship is sailing in a complex water environment, the ship will vibrate in vertical and horizontal directions due to the disturbance of the waves to the hull. As the roll is most obviously affected by wind and waves, the ship's overall stability. The impact is also the largest, in order to effectively improve the crew living environment in the cabin, the need for fin stabilizer on the ship to offset the swing to reduce its instability. In this paper, the working principle of the ship's fin is described, and its control model is analyzed. Through the improved genetic algorithm, the parameters of the controller are optimized. At the same time, the virtual marine operating environment is designed. The control effect is simulated, so that the reduction effect is optimal.
