Maximal unidirectional perturbation bounds for stability of polynomials and matrices

Minyue Fu, B. Ross Barmish
1988 Systems & control letters (Print)  
Given a stable polynomial or matrix, we consider a class of umdirectional perturbations. In this note, we provide a closed form for the maximal perturbation bounds under which stability is preserved.  ...  The results are then used to derive a closed form for the maximal stability box around the coefficients of a nominally stable polynomial.  ...  Kehui Wei for discussion of the proof of Theorem 3.2.  ...

2020 arXiv   pre-print
For this, we consider a family of unbounded regions defined in terms of Linear Matrix Inequalities (so-called LMI regions).  ...  We study the problem when the localization of a matrix spectrum in an unbounded LMI region is preserved under specific multiplicative and additive perturbations of the initial matrix.  ...  We note that [34] provides necessary and sufficient conditions for the multiplicative D-stability of a 4 × 4 matrix resorting to the Routh-Hurwitz criterion, but the method appears too complicated to  ...

2013 Mathematical Problems in Engineering  
Dynamical systems and control are one of the most active areas, and several authors focused on the stability of fractional order systems.  ...  Nevertheless, due to the multitude of efforts in a short period of time, contributions are scattered along the literature, and it becomes difficult for researchers to have a complete and systematic picture  ...  The work was done in the framework of cooperation between Belarusian State University and University La Laguna. The work is partly supported by Project MTM2010-16499 from the Government of Spain.  ...
