  • Abstract
    The circle criterion provides a convenient method of testing stability in nonlinear feedback systems. The need for computer computation of the relative stability conditions for the Nyquist plot can be avoided by using a logarithmic gain-phase plot on the Nichols chart. The results of this technique agree within about 1% with those obtained from a computer solution of the Nyquist plot.
