摘　　要：传统船舶动力定位控制算法,在动力输出参量耦合情况下,存在动力阈值系数定位误差过大的问题。导致后续控制变量周期变化不稳定,无法准确控制船舶全局动力输出。为了解决上述动力定位控制问题,提出模糊控制方法的水面船舶动力定位控制。基于模糊控制方法的广域性,对动力控制参量进行模型计算;根据模型完成对动力变量目标位置定位量的优化。最后,根据优化阈值利用模糊神经算法,完成对输出控制量策略的更新,实现提升动力定位控制精准度,减小控制误差的效果。通过与传统算法的效果对比表明:提出的控制方法,具有定位速度快、精度高、资源消耗小的特点,更适合实际船舶动力定位控制场景的应用。Traditional ship dynamic positioning control algorithm has the problem of excessive dynamic threshold coefficient localization error in the power output parameter coupling.Lead in subsequent control variable cycle instability,unable to accurately control the ship global power output.In order to solve the above power positioning control problem,the fuzzy control method of water ship is proposed.Based on the wide domain of fuzzy control method,calculate the power control parameter,optimize the target position according to the model,the fuzzy neural algorithm updates the output control strategy to improve the power positioning control accuracy and reduce the control error.By comparison with the traditional algorithm,the proposed control method has fast positioning speed,high precision and small resource consumption,which is more suitable for the application of the actual ship dynamic positioning control scenario.
