摘要
为应对复杂海况的非线性干扰,针对动态变化海况作出相应策略调整,提出突发事故下复杂海况救助船姿态稳定性控制方法。构建基于模糊PID控制救助船姿态稳定性控制模型,考虑救助船行驶过程中风干扰、海流干扰2种突发事故干扰,获取救助船姿态变化结果,通过模糊PID控制针对救助船姿态变化偏差实时调整救助船姿态稳定性控制量,实现救助船姿态稳定性控制。通过实验验证,该方法能适应复杂海况,在不同等级海况下,救助船最大横摇角均在3.5°以内,最大横向位移偏差均小于2 m,救助船稳定性均在97%以上,翻船率稳定在2.5%以下,能有效确保复杂海况救助船安全性,有助于实现海上突发事故顺利救援。
To cope with the nonlinear interference of complex sea conditions,corresponding strategy adjustments are made for dynamically changing sea conditions,and a method for controlling the atitude stability of rescue ships in complex sea conditions under sudden accidents is proposed.Construct a fuzzy PID control model for the attitude stability control of rescue ships,considering two types of sudden accident interference during the navigation process:wind interference and ocean current interference.Obtain the results of the rescue ship's attitude change,and adjust the attitude stability control quantity of the rescue ship in real time through fuzzy PID control to achieve attitude stability control of the rescue ship based on the deviation of the rescue ship's attitude change.Through experimental verification,this method can adapt to complex sea conditions.Under different levels of sea conditions,the maximum roll angle of rescue ships is within 3.5°,the maximum lateral displacement deviation is less than 2 m,the stability of rescue ships is above 97%,and the capsizing rate is stable be-low 2.5%.It can effectively ensure the safety of rescue ships in complex sea conditions and help achieve smooth rescue of sudden accidents at sea.
