let's say i build a model at Simulink then i want to get the Transfer Function of that model.

then i will put i step response to see the output the i will make a controller on the TF with SisoTool.

So how can i get the TF of a model.

Simulink Control Design has a linearization functionality which will give you a state-space (or transfer function) representation of a model at the selected operating point and input/output signals.

https://www.mathworks.com/help/slcontrol/ug/linearize-simulink-model.html

Note also that you can start the Control System Designer (formerly known as SISOTOOL) directly from a Simulink model by selecting Analysis > Control Design > Control System Designer from the model's menu.

... in the same menu you will find the Linear Analysis Tool (for linearization), as well as other control design tools that may be useful depending on what you're doing.
