control.matlab.damp(sys, doprint=True)¶ Compute natural frequency, damping ratio, and poles of a system
The function takes 1 or 2 parameters
- Parameters
sys (LTI (StateSpace or TransferFunction)) – A linear system object
doprint – if true, print table with values
- 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.
