Parameter optimization of ship 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的参数优化方法，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 based on a genetic algorithm is proposed.
    Methods First, based on the ship seakeeping and gyro dynamics theories, the passive control system of the anti-roll gyro is precisely modeled, containing an electromagnetic torque model of the precession motor. Second, to address the balance between rocking reduction efficiency and system chatter, a parameter optimization method for the onboard anti-roll gyro control system based on a genetic algorithm is proposed. The performance of the system under the fourth level of typical sea conditions is then simulated and verified by Matlab/Simulink.
    Results The simulation results show that the optimized system has superior performance, with a highest rocking reduction efficiency of 97.44% and no obvious chatter in the precession system.
    Conclusions The results of this study can provide useful references for the design and optimization of onboard anti-roll gyro control systems.
