D-stability of polynomial matrices

open access: yesInternational Journal of Control, 2001
Necessary and sufficient conditions are formulated for the zeros of an arbitrary polynomial matrix to belong to a given region D of the complex plane. The conditions stem from a general optimization methodology mixing quadratic and semidefinite programming, LFRs and rank-one LMIs.

Polynomial Stability and Polynomial Instability for Skew-Evolution Semiflows

Results in Mathematics, 2019
Let \(\mathbb{X}\) be a Banach space and let \(T:=\{(t,s):t\geq s\geq0\}\). Let \(\mathcal{M}\) be a metric space. Consider a skew-evolution semiflow \((\Phi,\zeta)\), where \(\zeta:T\times\mathcal{M}\to\mathcal{M}\) and \(\Phi:T\times\mathcal{M}\to \mathcal{L}(\mathbb{X})\).

Stability Analysis of Polynomial-Fuzzy-Model-Based Control Systems Using Switching Polynomial Lyapunov Function

open access: yesIEEE Transactions on Fuzzy Systems, 2013
This paper investigates the stability problem of polynomial-fuzzy-model-based control system, which is formed by a polynomial fuzzy model and a polynomial fuzzy controller connected in a closed loop. A switching polynomial Lyapunov function consisting of

SOS-Based Stability Analysis of Polynomial Fuzzy-Model-Based Control Systems Via Polynomial Membership Functions

open access: yesIEEE Transactions on Fuzzy Systems, 2010
This paper presents stability analysis of polynomial fuzzy-model-based (FMB) control systems using the sum-of-squares (SOS) approach. Recently, stability analysis of the polynomial fuzzy-control systems, which is a generalized form of the well-known ...

Stability and stabilization of polynomial dynamical systems using Bernstein polynomials

Proceedings of the 18th International Conference on Hybrid Systems: Computation and Control, 2015
In this work, we examine relaxations for the stability analysis and synthesis of stabilizing controllers for polynomial dynamical systems. It is well-known that such problems can be naturally solved using a reduction to polynomial optimization problems.
