TMS320F280049C: TIDM-2008/TIDM-1007

Part Number: TMS320F280049C
Other Parts Discussed in Thread: TIDM-1007

TIDM-2008/TIDM-1007参考设计中,Lab2中的电流环控制逆变等式如下:

问题1:为什么电流环Gi补偿器的输入是 反馈测量值减去参考设定值(ac _ cur _meas ac _ cur _ref _inst)?这与实际的补偿器误差计算方式是相反的。

问题2:duty1PU的输出由电流环输出、电压前馈两部封相加组成,电压前馈= ac _ vol_ sensed /  vBus _ sensed,电流环输出部分为什么要除以vBus _ sensed?
