Performing ac sweep (small-signal analysis) for a resonant converter in MATLAB

Hi there,

I was working on a project which involves closed-loop design for a resonant converter using the SISO design tool of MATLAB. Could anyone tell me what is the command / option to perform an ac sweep analysis (small-signal perturbation) of resonant converter and obtain its transfer function in MATLAB?

Based on this, I need to export the frequency response and phase response to SISO Design tool and design a PI / PID controller of resonant converter.

Can anyone help me on this topic?
