Robustness of Multiloop Linear Feedback System,

Abstract

This paper presents a new approach to the analysis of robustness or sensitivity of multiloop linear feedback systems. The properties of the return difference equation are examined using the concepts of singular values, singular vectors and the spectral norm of a matrix. A number of new tools for multiloop systems are developed which are analogous to those for scalar Nyquist and Bode analysis, providing a generalization of the scalar frequency-domain notions such as stability margins and M-circles.
