Help needed

Good day, hope you are well.

I have an assignment that needs me to create a Buck converter in PSCAD. I have created this, and it seems to be working. I now need to add in the feedback loop for voltage regulation and watch the duty ratio change as the voltage steps up from 12- 18 V and 18- 14 V but I can't seem to get this to work. Will you be able to look at this file for me and guide me in the right direction?

I am highly sorry but I can not assist with school work.

What I can advise as a general observation is to increase the time for the single level comparator as your PI controller may not be fast enough to change the DC output.
