The invention discloses a fishing boat stability control method and system adaptive to a storm environment, and relates to the technical field of fishing boat stability control. According to the method, a posture sensing module and a sea condition sensing module are installed on a fishing boat, and hull posture data and sea condition data are obtained in real time; and prediction of future wind wave acting force Fwave is carried out in combination with a nonlinear ship body swing model and a long and short term memory (LSTM) network model. According to the technical scheme, the influence of the current sea condition on the hull stability can be effectively evaluated, a deck support self-adaptive adjustment mechanism is triggered in time, the deck support force is adjusted, and the hull stability is optimized. When the wind wave acting force exceeds the preset wind wave threshold value Fth, the deck supporting force can be automatically adjusted, so that the rolling amplitude of a ship body is effectively reduced, and the stability and safety of fishing boat operation are ensured. Compared with the prior art, through real-time wind wave prediction and self-adaptive adjustment, the problem that the ship body is unstable due to wind wave changes is solved.

    本发明公开了一种自适应风浪环境的渔船稳定控制方法及系统,涉及渔船稳定控制技术领域,该方法通过在渔船上安装姿态感知模组和海况感知模组,实时获取船体姿态数据和海况数据,并结合非线性船体摇摆模型和长短时记忆网络模型LSTM进行未来风浪作用力Fwave的预测。该技术方案能有效评估当前海况对船体稳定性的影响,及时触发甲板支撑自适应调整机制,调整甲板支撑力,优化船体的稳定性。在风浪作用力超出预设的风浪阈值Fth时,本发明能自动进行甲板支撑力的调整,从而有效降低了船体横摇幅度,确保了渔船作业的稳定性与安全性。与现有技术相比,本发明通过实时风浪预测与自适应调整,避免了因风浪变化带来的船体不稳定问题。
