How do you find the damping of a transfer function?

Detailed Solution. Concept: The damping ratio symbol is given by ζ and this specifies the frequency response of the 2nd order general differential equation. Using the damping ratio, one can know the damping level of a system.

What is damping ratio in transfer function?

The damping ratio is a measure describing how rapidly the oscillations decay from one bounce to the next. The damping ratio is a system parameter, denoted by ζ (zeta), that can vary from undamped (ζ = 0), underdamped (ζ < 1) through critically damped (ζ = 1) to overdamped (ζ > 1).

How do you find the damping ratio of a transfer function in Matlab?

[ wn , zeta ] = damp( sys ) returns the natural frequencies wn , and damping ratios zeta of the poles of sys . [ wn , zeta , p ] = damp( sys ) also returns the poles p of sys .
