DC-DC buck converter Simulink model shows to be quite different from circuit system. How do I fix this?

The problem I am facing is that the results of the circuit systems ("Real buck" show to be signifcantly different than the same controllers used on the transfer function representation of the system.
In short: the transfer function system and circuit model differ in results when controlled by the same controller.
The first image presents the results of the system.
The second image presents the simulink used to gather results.
The third image presens the buck converter used for the system
If there are any questions please feel free to ask. Rl is reinforcement learnign which was used to get the PID values for first system.
note open the images fully if possible, I can also provide zip file of the simulink
