Abstract :
The application of an inverse Nyquist diagram to the study of servomechanism performance is discussed. The use of the inverse plane has some advantages over the customary procedure. It is shown that system stability may be studied in a manner analogous to the conventional Nyquist method. The system frequency response and the effect of system parameters upon performance may be determined by simple graphical methods.
