Closed loop bode plot

Can anyone help ?.
I am trying to plot the bode of closed loop output impedance and I am failing really hard.
I can plot the open loop stuff just fine, only issue is with the closed loop.
I am sensing the output voltage with two resistors. feeding the required voltage value to an analog PID, then feeding the control signal onto a comparator with carrier signal.
The model is assuming that all components are ideal.

Hi @AMANORA,

Please find the attached schematic files which dealt with input and output impedance of peak current mode controlled dc-dc buck converter.

Hope this can help with your converter!
