船舶变速恒频风电机组电压的鲁棒性,需要控制在一定数据浮动区间内,传统控制方法的鲁棒性控制较弱,为此提出船舶变速恒频风电机组电压的鲁棒性控制方法。构建电压鲁棒性控制数学模型,使用双PWM协调控制策略,将变速恒频风电机组电压区分为动态电压以及稳态电压。利用传递函数计算电压的鲁棒性区间,完成稳态电压下鲁棒性控制;使用多态原则计算动态电压下鲁棒性区间,实现动态电压鲁棒性控制。实验数据表明,设计的船舶变速恒频风电机组电压的鲁棒性控制方法比传统电压鲁棒性控制方法的控制精度高一个数据集,并且具备极高的有效性。

Ship the robustness of variable speed constant frequency wind power generator voltage, the need to control within a certain range of floating data, the traditional control method for robust control is poor, therefore put forward ship the robustness of variable speed constant frequency wind power generator voltage control method. A robust dynamic control mathematical model of voltage is built, and a dual PWM coordinated control strategy is used to distinguish the voltage of the variable speed constant frequency wind turbine generator to the dynamic voltage and the steady-state voltage. The robustness of the voltage is calculated by using the transfer function. Dynamic voltage robustness control is realized by using the multi-state principle. Experimental data show that the design of variable speed constant frequency wind power generator voltage robust control method for robustness than the traditional voltage control method to improve control precision of a data set, and have high effectiveness.
