针对船用风力发电机快速响应控制问题,采用传统控制方法受到内部环境和人为因素影响,导致控制效果较差,提出了基于模糊算法的船用风力发电机MPPT快速响应控制。根据船用风力发电机MPPT结构,分析MPPT快速响应工作原理,利用大量实际数据归纳总结出控制规则,可快速响应船舶外部环境变化,采用双输入单输出控制方式,将输入输出量转化为模糊集论域,使用三角隶属度函数来表示各个变量,由此完成船用风力发电机MPPT快速响应控制。通过实验结果可知,该方法最高控制效果可达到98%,可达到有效控制风力发电机振动的目的。

In view of the fast response control problem of the marine wind turbine, the traditional control method is affected by the internal environment and human factors, resulting in the poor control effect. The MPPT fast response control of the marine wind turbine based on the fuzzy algorithm is proposed. According to the MPPT structure of the marine wind turbine, the principle of MPPT fast response is analyzed, and the control rules are summarized and summed up by a large number of actual data, which can quickly respond to the change of the ship's external environment, and use the dual input and single output control mode to convert the input and output into the fuzzy set domain, and use the trigonometric membership function to express each other. Variable, thus completing the MPPT fast response control of marine wind turbine generator.The experimental results show that the maximum control effect of this method can reach 98%, which can effectively control the vibration of wind turbine.
