- Go directly to a linearized model (TF or SS representation) via Simulink Control Design toolbox. You can linearize model around a particular operating point or set of operating points.
- If you want to get a frequency sweep and then convert to transfer function. I would recommend get a frequency response estimate through our Simulink Control Design toolbox and then pass that data into the System Identification toolbox to get an estimated model of your system
How to use curve fitting to get transfer function in frequency domain?

Hi all,
I have the data of sweep frequency scan of my circuit, both magnitude and phase. I am trying to use matlab curve fitting to obtain a transfer function from it. Can someone give help on this? Since I don't see curve fitting tool can import both magnitude and phase data in one fitting.

Hi Siyu,
Rather than go through the Curve Fitting toolbox, I recommend one of two other avenues.
