说明：  该程序为MATLAB的m文件，用于设计单相LCL并网逆变器控制器参数，控制方式为电容电流和入网电流控制方式，只需输入LCL滤波参数和直流侧电压可计算出双闭环控制器参数。
(The program is the m file of MATLAB, which is used to design the controller parameters of the single-phase LCL grid connected inverter. The control mode is the control mode of the capacitance current and the net current. The parameters of the double closed loop controller can be calculated only by the input of the LCL filter parameters and the DC side voltage.)
