Robust Stability of Quasipolynomials: Vertex Tests and Extensions
نویسندگان
چکیده
In this paper we study the robust stability of uncertain quasipolynomials, whose coef£cients may vary in a certain prescribed range. We consider speci£cally the co-called interval and diamond quasipolynomials, and our goal is to develop vertexand edge type-conditions for these quasipolynomial families to be robustly stable independent of delay. Moreover, we also present a number of extensions to more general uncertain quasipolynomials, including both frequency-sweeping and vertex/edge type results.

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 کاملA Semi Analytic Approach to the Robust Stability of Quasipolynomials
A semi-analytic tool for the study of the robust stability of time delay systems is presented. The approach is based on graphical methods. The conditions of the Finite Nyquist Theorem for quasipolynomials given in (Santos et al., 2003b) are improved. The Finite Inclusions Theorem for polytopic and interval quasipolynomials families is derived. An algorithm describing how to apply this new techn...
متن کاملThe edge theorem and graphical tests for robust stability of neutral time-delay systems
Alrstract--We consider the robust stability problem for a class of uncertain neutral time-delay systems where the characteristic equations involve a polytope ~ of quasipolynomials of neutral type. Given a stability region D in the complex plane our goal is to find a constructive technique to verify the D-stability of ~ (i.e. to verify whether the roots of every quasipolynomial in ~ all belong t...

In this paper, a robust autopilot is proposed using stable interpolation based on Youla parameterization. The most important condition of stable interpolation between local controllers is the preservation of stability so that each local controller can ensure stability for an open neighborhood around a nominal point. The proposed design used fixed-order robust controller with parameter-dependent...
متن کاملRobust Stabilization of a Main Irrigation Canal Pool via Fractional Order Pi Controller: a Graphical Investigation
This contribution is focused on graphical investigation of robust stability for a feedback control loop containing the parametrically uncertain second order time-delay model of a main irrigation canal pool and a fractional order PI controller. The robust stability of the family of fractional order closed-loop characteristic quasipolynomials is analyzed by means of the sampled value sets and app...
