PhaseMargins
PhaseMargins
[
sys
]
gives the phase margins of a linear time-invariant system
sys
.
MORE INFORMATION
The system
sys
can be specified as
TransferFunctionModel
,
StateSpaceModel
, or a function
m
in the complex variable
var
.
PhaseMargins
returns
, where
are the gain crossover frequencies in radians per time unit, and
are the phase margins in radians.
PhaseMargins
has the same options as
GainPhaseMargins
.
PhaseMargins
has the attribute
