Abstract :
THIS ARTICLE PRESENTS two general concepts which are very valuable in analyzing nonlinear servomechanisms. A graphical procedure is introduced by which the frequency response of a nonlinear closed-loop system can be determined from the describing function. The theory is even valid for the general describing function which is both amplitude and frequency dependent (Fig. 1).
