GainMargins
GainMargins[lsys]
gives the gain margins of the linear time-invariant system lsys.
Details and Options
- The system lsys can be a TransferFunctionModel or a StateSpaceModel.
- The gain margins are the reciprocals of the magnitude of lsys at the phase crossover frequencies.
- At the phase crossover frequencies lsys has phase
. - GainMargins returns {{ωp1,g1},{ωp2,g2},…}, where ωpi are the phase crossover frequencies, and gi are the absolute values of the gain margins.
- GainMargins has the same options as GainPhaseMargins.
- GainMargins has the attribute Listable.
-
FeedbackType "Negative" the feedback type Method Automatic method to use SamplingPeriod None the sampling period
