Spectrum-based stability analysis and stabilization of a class of time-periodic time delay systems
Wim Michiels, Luca Fenzi
We develop an eigenvalue-based approach for the stability assessment and stabilization of linear systems with multiple delays and periodic coefficient matrices. Delays and period a…

Polynomial (chaos) approximation of maximum eigenvalue functions: efficiency and limitations
Luca Fenzi, Wim Michiels
This paper is concerned with polynomial approximations of the spectral abscissa function (the supremum of the real parts of the eigenvalues) of a parameterized eigenvalue problem,…
