模糊控制理论在船舶操纵中的应用

Application of fuzzy control theory in ship maneuvering

为使船舶行进水动力与预设动力数值曲线较好贴合,针对模糊控制理论在船舶操纵中的应用情况展开研究。按照模糊滤波监测器的运行原理,建立完整的船舶航向控制表达式,再根据浆力操纵量指标、舵力操纵量指标的数值计算结果,构建标准的船舶操纵运动模型,完成对模糊控制理论在船舶操纵中应用情况的研究。实验结果表明,模糊控制理论能够促使船舶行进水动力数值与预设动力数值曲线更好贴合,与变论域模糊控制技术相比,更符合稳定操纵船舶的实际应用需求。

In order to test the fit degree between the ship’s running water power and the preset power numerical curve,the application of fuzzy control theory in ship maneuvering is studied. According to the operation principle of fuzzy filter monitor, a complete expression of ship course control is established, and then a standard ship maneuvering motion model is constructed according to the numerical calculation results of pulp force maneuvering index and rudder force maneuvering index, so as to complete the research on the application of fuzzy control theory in ship maneuvering. The results show that the fuzzy control theory can make the ship’s hydrodynamic value fit better with the preset dynamic value curve. Compared with the variable universe fuzzy control technology, it is more in line with the practical application needs of stabilizing the ship.
