On Robust Stability of Complex Polynomials
نویسندگان
چکیده
Complex polynomial family with coeÆcients dependent aÆnely on a complex uncertain parameter is considered in this paper. New test for robust Hurwitz stability of a line segment is proposed. Simple numerical routine is presented for computation of a stability region in the complex parameter plane. The relationship between the H1 norm of a stable rational function and a stability bound on the complex uncertain parameter is highlighted. Possible utilization of this result for the H1 norm computation is outlined. Relation to positiveness of a two-sided (discretetime) polynomial matrix is discussed.

The Optimum Radius of the Robust Stability of Schur Polynomials
The problem of the Robust Stability of Schur Polynomials is investigated. Recently, a new approach based on Rouche's theorem of the classical complex analysis has been adopted for the solution of this problem. In this paper, an improvement of this solution is presented. This is the optimum solution of the Robust Stability problem of Schur Polynomials and is obtained by solving a minimization pr...
متن کامل2-d Algebraic Test for Robust Stability of Quasipolynomials with Interval Parameters
Determining the robust stability of interval quasipolynomials leads to a NP problem: an enormous number of testing edge polynomials. This paper develops an efficient approach to reducing the number of testing edge polynomials. This paper solves the stability test problem of interval quasipolynomials by transforming interval quasipolynomials into two-dimensional (2-D) interval polynomials. It is...
متن کاملSome Necessary Conditions for Schur Stability of Polynomials
This paper concerns the Schur stability of polynomials. Firstly necessary conditions are presented for the Schur stability of complex polynomials with fixed coefficients based on the discrete Hermite-Biehler theorem. Then the result is applied to obtain necessary conditions for the robust Schur stability of real interval polynomials.
متن کاملRobust stability of fractional order polynomials with complicated uncertainty structure
The main aim of this article is to present a graphical approach to robust stability analysis for families of fractional order (quasi-)polynomials with complicated uncertainty structure. More specifically, the work emphasizes the multilinear, polynomial and general structures of uncertainty and, moreover, the retarded quasi-polynomials with parametric uncertainty are studied. Since the families ...
متن کاملEdge Theorem for Multivariable Systems
Motivated by the seminal theorem of Kharitonov on robust stability of interval polynomials[1, 2], a number of papers on robustness analysis of uncertain systems have been published in the past few years[3, 4, 5, 6, 7, 8, 9, 10]. Kharitonov’s theorem states that the Hurwitz stability of the real (or complex) interval polynomial family can be guaranteed by the Hurwitz stability of four (or eight)...
