Constant current using synchronous buck boost converter

Hey Guys,
I'm in real need of help with my synchronous buck converter. I have stepped down my DC voltage however to get a constant current i had to feedback error to the PID controller which will control the duty cycle of the Switching regulator of Buck converter. I have used proper circuit connection in proteus however i couldn't tune the PID properly. I have tried all method Ziegler Nicholas method as well. So any help with my project would be a great help. Below is cirucit of cc-cv which i downloaded from mathworks MATLAB. It does work but when i convert it into cc mode only then it fails. cccv1.JPG
