摘　　要：船舶在航行过程中受到波浪影响容易发生倾覆事故,对人员安全造成极大威胁。本文在研究Conolly船舶横摇模型的基础上,提出一种基于液压控制技术的船舶自动应急抗倾覆装置的设计方案,使用减摇鳍来降低船舶的横摇幅度,并通过DSP控制器+Conolly船舶横摇模型的闭环控制方案实现船舶自动应急抗倾覆的目的。通过升力传感器、行程反馈和角度反馈的信号,然后计算出最优的控制信号发送给液压缸并驱动减摇鳍,产生与船舶横摇方向相反的力矩,系统能够动态响应海况变化和船舶运动,对自动应急抗倾覆装置进行仿真,结果表明,系统具有较好的适应性和实时性。Ships are susceptible to capsizing accidents due to the impact of waves during navigation,posing a significant threat to the safety of personnel.Based on the study of the Conolly ship rolling model,this paper proposes a design scheme for an automatic emergency anti-capsizing device for ships that utilizes hydraulic control technology.The scheme suggests using fin stabilizers to reduce the roll amplitude of the ship and employs a closed-loop control strategy involving a DSP controller and the Conolly ship rolling model to achieve the purpose of automatic emergency anti-capsizing.By receiving signals from the lift force sensor,stroke feedback,and angle feedback,the system calculates the optimal control signal,which is then sent to the hydraulic cylinder to drive the fin stabilizer.This generates a torque opposite to the direction of the ship's roll.The system can dynamically respond to changes in sea conditions and ship movement.A simulation of the automatic emergency anti-capsizing device was conducted,and the results indicate that the system has good adaptability and real-time performance.
