PhaseMargins
PhaseMargins[lsys]
gives the phase margins of the linear time-invariant system lsys.
Details and Options
- The system lsys can be a TransferFunctionModel or a StateSpaceModel.
- The phase margins are phase lags needed to make the phase
at the gain crossover frequencies. - At the gain crossover frequencies, the gain of lsys is unity.
- PhaseMargins returns {{ωg1,p1},{ωg2,p2},…}, where ωgi are the gain crossover frequencies, and pi are the phase margins in radians.
- PhaseMargins has the same options as GainPhaseMargins.
- PhaseMargins has the attribute Listable.
-
FeedbackType "Negative" the feedback type Method Automatic method to use SamplingPeriod None the sampling period
