Natural frequency and damping ratio
damp(sys)
[Wn,zeta]
= damp(sys)
[Wn,zeta,P]
= damp(sys)
damp(
displays
a table of the damping ratio (also called damping factor),
natural frequency, and time constant of the poles of the linear model sys
)sys
.
For a discretetime model, the table also includes the magnitude of
each pole. Frequencies are expressed in units of the reciprocal of
the TimeUnit
property of sys
.
Time constants are expressed in the same units as the TimeUnit
property
of sys
.
