In this paper, minimum gain of an operator is introduced. Moreover, some of its properties are presented. It is proved that the minimum gain of a strictly proper, stable, LTI system is zero. It isâ€¦ (More)

In this technical note, new methods are proposed to compute upper bounds on the <i>L</i> <sub>1</sub> , <i>L</i> <sub>2</sub> and <i>L</i> <sub>infin</sub> induced operator norms of continuous-timeâ€¦ (More)

A new framework is developed to study the robust stability of nonlinear systems based on operator-theoretic methods. First new representation called zeta<sub>A</sub> for nonlinear systems isâ€¦ (More)

Abstract Quantitative Feedback Theory (QFf) method for Multi Input Multi Output (MIMO) systems divides design problem into some Single Input Single output (SISO) problems. In this method,â€¦ (More)

This work deals with the computation of upper bounds on the gap metric and the corresponding stability margin. The suggested bounds can be computed for a class of a nonlinear systems which satisfy anâ€¦ (More)
