Abstract:
In this work is looking off sufficiently
classes of matrixes stability on Vagevsky, i. e. stability matrixes
$P$ for that symmetrical matrix $P+P^{T}$ also stability. For this
family of matrixes is describes, that they material radius of
stability is appears smaller own number of matrix - $(P+P^{T})\backslash 2$.
This result is allows to define material radius of stability «over
stability» matrixes, i. e. they ia appears the matrixes stability on
Vashevskiy.
Keywords:matrix, stability, material radius, spectral norma, in stationary system.
