This paper investigates the effect of gain and phase margins (GPMs) on stability delay margin of a two-area load frequency control (LFC) system with constant communication delay. A gain-phase margin tester (GPMT) is introduced to the LFC system as to take into GPMs in delay margin ...
This robustness can be interpreted as gain and phase margins when a cone-bounded non-linearity is introduced in the loop. The condition imposed on the robustness sector that the feedback control will meanwhile minimize a quadratic performance index is also obtained.TSU-TIAN LEE & SHIOW-HARN LEE...
Characteristic gain loci of Kranc operators can be used to determine gain and phase margins of multi-rate sampled-data feedback systems.doi:10.1080/00207178608933635THOMPSONPETER M.Taylor & Francis GroupInternational Journal of ControlThompson, P.M., (1986) "Gain and phase margins of multirate ...
TheGain and Phase Margin Plotdoes not define default bounds. TheCheck Gain and Phase Marginsblock defines default bounds and enables these bounds for assertion. You can view the margins in a table or on a Bode, Nichols, or Nyquist plot. ...
First, the approach here bounds the sensitivity of the closed-loop transfer function for all frequencies, not just at the crossover frequencies where the gain and phase margins are satisfied. (It is possible that the gain and phase margin conditions are met with a given PI design, but ...
GainPhaseMargins[lsys] gives the gain and phase margins of the linear time-invariant system lsys.
Gain and Phase Margins Changes in the loop gain are only one aspect of robust stability. In general, imperfect plant modeling means that both gain and phase are not known exactly. Because modeling errors are most damaging near the gain crossover frequency (frequency where open-loop gain is 0dB...

The dynamic uncertainties are bounded by some norm, that is usually normalized by unity. One useful application of dynamic ...
