Hello Tomas,
you can do frequency analysis using the power gui block here: https://www.mathworks.com/help/physmod/sps/powersys/ug/simulating-variable-speed-motor-control.html#f1-11898
but you can also use the matlab fft command to calculate your current's frequency response: https://www.mathworks.com/help/matlab/ref/fft.html
there are other ways such as using the control systems toolbox for linear analysis or the signal processing toolbox to automatically do this for you.
Regards,
Joel
