Parameter optimization of ship's anti-roll gyro control system based on genetic algorithm

    摘要
  • 摘要:
    目的 为了提高船载减摇陀螺的工作性能，提出一种基于遗传算法的减摇陀螺被动控制参数优化方法。
    方法 首先，基于船舶耐波性和陀螺动力学理论，对船载减摇陀螺的被动控制系统进行精细化建模，并引入进动阻尼电机的电磁转矩模型；然后，针对船载减摇系统减摇效率与进动阻尼系统抖振之间的平衡问题，提出基于遗传算法的船载减摇陀螺控制系统参数优化方法，并采用Matlab/Simulink平台对四级典型海况下的减摇系统性能进行仿真验证。
    结果 仿真结果表明，优化后的船载减摇陀螺控制系统具有更加优异的性能，其减摇效率最高可达97.44%，且进动阻尼系统无明显抖振。
    结论 研究成果可为船载减摇陀螺控制系统的设计与优化提供参考。

     

    Abstract:
    Objectives In order to improve the performance of the anti-roll gyro, a passive control parameter optimization method of the anti-roll gyro based on genetic algorithm is proposed.
    Methods Firstly, based on the theory of ship seakeeping and gyro dynamics, the passive control system of anti-roll gyro is precisely modeled, which contains the electromagnetic torque model of the precession motor. Secondly, to address the balance between the rocking reduction efficiency and system chatter, the parameter optimization method of onboard anti-roll gyro control system based on genetic algorithm is proposed. The performance of the system under the fourth level of typical sea condition is simulated and verified by Matlab/Simulink.
    Results The simulation results show that the optimized system has more remarkable performance, with the highest rocking reduction efficiency of 97.44%, and no obvious chatter in the precession system.
    Conclusions The research results can be used as a reference for the design and optimization of the onboard anti-roll gyro control system.
