Damping ratio computing from a MATLAB plot
Afficher commentaires plus anciens
Hi Altruists,
I have a MATLAB plot which I exported from Digsilent software and I am willing to calculate the damping ratio and natural frequency. What are the commands for that, may I know?

Use prony analysis using prony Toolbox. That will give your requirements.

For natural frequency you need to look into fft.
Damping ratio can be calculated using logarithamic decrement approach. https://en.wikipedia.org/wiki/Logarithmic_decrement
