Abstract :
Many robustness measures are computed in the frequency domain, such measures include gain margin, phase margin, Popov and circle criteria, closed-loop resonance peak, and bandwidth. All of these measures may be computed directly using a simple frequency domain interpolation calculation, by means of a polynomial root solver
