STABILITY OF NONLINEAR CONTROL SYSTEMS BY THE SECOND METHOD OF LIAPUNOV

Abstract

A report is made on the use of the second ethod of Liapunov as a tool for stability analysis of nonlinear control systems. A pole-shifting technique and a zero-shifting technique, extending the applicability of simplified stability criteria to systems that are stable for sufficiently high and/or sufficiently low values of loop gain, in a closed loop system, are proposed. New simplified stabilit criteria have been developed which incorporate the changes in the canonic form of differential equations caused by the application of the zero-shifting technique.
