TMS320F28069M: How to implement a CURRENT MODE CONTROL combining the average current and peak current - F28069M BOOSTXL-BUCKCONV

Part Number: TMS320F28069M
Other Parts Discussed in Thread: BOOSTXL-BUCKCONV

Hi, this is my first time in this forum.
I have acquired and tested the F28069M BOOSTXL-BUCKCONV kit, the both examples OPEN LOOP and CLOSED LOOP works properly in this kit.

Now I have the following question:
I have modified the voltage ADC channel (ch1) by the average current ADC channel (ch2) and working as CMC,
but I can't get the output voltage to work according to the set current.

But, I can't get the output voltage to work according to the current set in the control system.
( e.g. if the control follows the waveform of a signal, the output voltage starts to decrease and loses coherence with the output current.)
I think this is because the control only considers the average current but not the maximum peak current. How can I combine the average current with the peak currents to generate the rigth reference input value for the control system????
