Hi,
I am trying to get some transfer function fit to this data using the identification app, but it doesn't give me anything better than 50% fit.

This is the command I use:
mw1 = tfest(z1,15,20,20,'Ts',Ts)
Can somebody give any hints or advice. Data is attached.
Thanks a lot

Which release of MATLAB are you using? Starting in R2016b, a new algorithm is used for faster and more accurate estimation.
