control.damp

control.damp(sys, doprint=True)[source]

Compute natural frequency, damping ratio, and poles of a system

The function takes 1 or 2 parameters

Parameters
Returns

  • wn (array) – Natural frequencies of the poles

  • damping (array) – Damping values

  • poles (array) – Pole locations

See also

pole

Notes

If the system is continuous,

wn = abs(poles) Z = -real(poles)/poles.

If the system is discrete, the discrete poles are mapped to their equivalent location in the s-plane via

s = log10(poles)/dt

and

wn = abs(s) Z = -real(s)/wn.
