Non-negative matrices and their structured singular values

Izvestiya Vysshikh Uchebnykh Zavedenii. Matematika, 2023
In this article, we present new results for the computation of structured singular values of non-negative matrices subject to pure complex perturbations. We prove the equivalence of structured singular values and spectral radius of perturbed matrix (M∆).

Structured singular values with nondiagonal structures. II. Computation

IEEE Transactions on Automatic Control, 1996
This is a continuation of the paper on generalized structured singular values [the authors, IEEE Trans. Autom. Control 41, No. 10, 1507-1511 (1996; Zbl 0879.93012)]. Here a numerical method for calculating this value is formulated. It consists of computing an upper norm bound scaled by a similarity transformation. This bound is equal to the generalized

Structured singular values with nondiagonal structures. I. Characterizations

IEEE Transactions on Automatic Control, 1996
[Part II is reviewed below (see Zbl 0879.93013).] The structured singular value is used is robustness analysis and design of feedback systems with multiple sources of modeling uncertainty. Here a generalized structure singular value is introduced and studied as a robust stability measure for a general class of uncertainties.

Computing the Structured Singular Value

SIAM Journal on Matrix Analysis and Applications, 1992
Discussing some problems of multivariable control theory, the author begins to examine some algorithms to compute the structured singular value due to \textit{J. C. Doyle} [Analysis of feedback systems with structured uncertainties. Proc. IEE-D 129, No. 6, 246-250 (1982; MR 84a:93035)]; this notion, in particular, includes the largest singular value of
