Buck converter control malfunction

0 votes
Hi, I am trying to control a buck converter, I implemented voltage control method and designed it on paper first, checked the TF via matlab and everything seems accurate till now.

Now I try to simulate toe boost and the output voltage is the same as the input voltage and I am really puzzled, I checked the buck analog control demo and copy pasted some stuff from there and still I get the same output.

I am thinking maybe the issue is from the op amp circuit, but I dont know how to navigate that.

thanks :)

I attached the schematic, the output from the scope and the project.

One point I could see is that the op amp power supply is not connected to ground. Could you please explain more about why you are adding some constant to modulating signal?
