Quadratic Matrix Inequalities and Stability of Polynomials
New relations are established between various matrix inequalities for testing stability of a scalar polynomial. These inequalities are quadratic functions of the coefficients of the polynomial, and linear (LMI) in ...

An LMI condition for robust stability of polynomial matrix polytopes.
A sufficient LMI condition is proposed for checking robust stability of a polytope of polynomial matrices. It hinges upon two recent results: a new approach to polynomial matrix stability analysis and a new robust stability...
