چکیده

A new condition for a polynomial ( ) to be a local convex direction for a Hurwitz stable polynomial ( ) is derived. The condition is in terms of polynomials associated with the even and odd parts of ( ) and ( ), and constitutes a generalization of Rantzer’s phase-growth condition for global convex directions. It is used to determine convex directions for certain subsets of Hurwitz stable polynomials.

Constructing convex directions for stable polynomials

New constructions of convex directions for Hurwitz-stable polynomials are obtained. The technique is based on interpretations of the phase-derivative conditions in terms of the sensitivity of the root-locus associated with the even and odd parts of a polynomial.

Stability of polynomials with conic uncertainty

In this paper, we describe a conic approach to the stability theory of uncertain polynomials. We present necessary and sufficient conditions for a conic set p0 + K of polynomials to be Hurwitz stable (K is a convex cone of polynomials of degree ≤ n and deg p0 = n). As analytical tools we derive an edge theorem and Rantzer type conditions for marginal stability (semi-stability). The results are ...

Some Remarks on the -stability for Families of Polynomials

Using Brouwer degree, we prove a more general version of the zero exclusion principle for families of polynomials and apply it to obtain very simple proofs of extensions of recent results on the Routh-Hurwitz and Schur-Cohn stability of families of polynomials. 1. Introduction It is well know that the problem of the stability of a linear diierence or differential system with constant coeecients...

Quantitative Bounds for Hurwitz Stable Polynomials under Multiplier Transformations

We extend results of Borcea and Brändén to quantitatively bound the movement of the zeros of Hurwitz stable polynomials under linear multiplier operators. For a multiplier operator T on polynomials of degree up to n, we show that the ratio between the maximal real part of the zeros of a Hurwitz stable polynomial f and that of its transform T [f ] is minimized for the polynomial (z + 1). For T o...
