Close loop bode plot

I tried to design buck converter using matlab m file. I input the transfer function and design the controller using k factor, I plot the bode plot of the transferred function and controller separately but I don't know how to combine both transfer function and controller to obtain close loop bode plot, can anyone guide me

If you have a model of the plant and a model of the controller, it's likely that all that's needed is the feedback command to come up with a model of the closed loop system. That model can be used with bode in the usual way to get the Bode plot of the closed loop system. Other functions that are useful for combining models are series, parallel, append, and connect, and possibly others. More generally start with Model Interconnection to learn more about the topic.
