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)
