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.
