In this paper, a new method is suggested to compute maximum achievable gain and phase
margins that can be achieved using a proportional controller. The method focuses on using
the Nyquist stability criterion and then applying a previously developed theorem which
allows determination of stabilizing gains. Methods for determining all stabilizing proportional
controllers that satisfy gain and phase margin constraints are also given.
