THD analysis of mathematical simulink model

I have done mathematical modelling of my system in simulink then how to perform the THD analysis

[Mathieu NOE]

hello

if you can export your simulink data to matlab workspace and with the Signal Processing Toolbox, you can use the thd function

Total harmonic distortion - MATLAB thd - MathWorks France

OK

Hi Pritham,

I understand that you need to perform the THD analysis in simunlink. The ‘powergui’ block can calculate the Total Harmonic Distortion (THD) of signal. In the FFT Analysis tool, you can select the signal for which you want to calculate the THD, and the tool will display the fundamental frequency and the THD.

You may refer the below links for more information related to ‘powergui’ and example on calculating the THD of signal using ‘powergui’
