光伏DC-AC 开发板里面很多参数,希望提供一些相关的资料参考,我想调整并网输出电流的大小,不知道需不需要修改电压控制环,电流控制环2P2Z里面的max,min系数啊。。

Erick,
谢谢你的回答,我是想二次开发,把功率扩大一倍,如果我要更换MOS管,和电感的话,那么PI的所有系数都要修改吗?
//Voltage loop
CNTL_2P2Z_CoefStruct1.b2 = _IQ26(-0.3682);
CNTL_2P2Z_CoefStruct1.b1 = _IQ26(0.01121);
CNTL_2P2Z_CoefStruct1.b0 = _IQ26(0.3794);
CNTL_2P2Z_CoefStruct1.a2= _IQ26(-0.869);
CNTL_2P2Z_CoefStruct1.a1= _IQ26(1.869);
CNTL_2P2Z_CoefStruct1.max = _IQ24(0.0); //4A 这里的4A是什么意思?电流不能大于4A的意思吗?max的系数怎么得出来的0.0--
CNTL_2P2Z_CoefStruct1.min = _IQ24(-0.4);
//Current loop for 52e-6 sample time
CNTL_2P2Z_CoefStruct2.b2 = _IQ26(-0.3938);
CNTL_2P2Z_CoefStruct2.b1 = _IQ26(0.1314);
CNTL_2P2Z_CoefStruct2.b0 = _IQ26(0.5253);
CNTL_2P2Z_CoefStruct2.a2= _IQ26(-0.01);
CNTL_2P2Z_CoefStruct2.a1= _IQ26(1.01);
CNTL_2P2Z_CoefStruct2.max = _IQ24(0.4);
CNTL_2P2Z_CoefStruct2.min = _IQ24(-0.4); //400 //这里注释的400呢是什么意思?
上面的是光伏DC-AC是电压环和电流环的参数。
谢谢
