Abstract

The inverse Nyquist array is a set of diagrams corresponding to the elements of the inverse of the open-loop transfer function of a control system. A number of theorems are proved which show how this array can be used to investigate the stability of multivariable control systems. The application of the array to the design of such systems is illustrated.
