damp

Natural frequency and damping ratio.

Syntax

[wn, zeta] = damp(sys)
[wn, zeta, p, T] = damp(sys)

Input argument

sys

LTI model.

Output argument

wn

Natural frequency of each pole: vector.

zeta

Damping ratio of each pole: vector.

p

Poles of the dynamic system model: vector.

T

Time Constant (seconds): vector.

Description

The function damp(sys) provides the natural frequencies (wn) and damping ratios (zeta) associated with the poles of the system represented by sys.

Example

sys = tf([2, 5, 1], [1, 0, 2, -6]);
[wn, zeta, p, T] = damp(sys)
