control.damp

control.damp(sys, doprint=True)

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
  • Algorithm
  • ———
  • 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.
