Stability of Two Variable Interval Polynomials via Positivity
نویسنده
چکیده
Stability criteria are proposed for two variable D polynomials having interval parameters in polynomic uncertain ty structures Both the left half plane and unit circle domains are considered Save for a minor condition the criteria reduce robust stability testing of D polynomials to testing positivity of only two polynomials The appealing feature of the new robustness criteria is that positivity testing can be carried out by using the e cient Bernstein minimization algorithms

2-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 کاملWronskian-based tests for stability of polynomial combinations
In this paper, a stability criterion based on counting the real roots of two specific polynomials is formulated. To establish this result, it is shown that a hyperbolicity condition and a strict positivity of a polynomial Wronskian are necessary and sufficient for the stability of any real polynomial. This result is extended to the stability study of some linear combinations of polynomials. Nec...
