Argument Principle Based Stability Conditions of a Retarded Quasipolynomial with Two Delays

چکیده
In the presented paper, we address a problem of the appropriate setting of a parameter in a selected quasipolynomial with two delay elements in order to ensure that all its zeros are located in the open left-half complex plane. The quasipolynomial can represent the dynamics of a system with internal delays and thus it can decide about system stability. In contrast to many other analyses, a non-delay real parameter is being to set. The argument principle (Mikhaylov criterion) is utilized for this purpose. Stability bounds for the parameter are found through proven lemmas, propositions and theorems. Key-Words: Stability, time-delay systems, characteristic quasipolynomial, argument principle, Mikhaylov criterion.

A Stability Test for Control Systems with Delays Based on the Nyquist Criterion
The aim of this contribution is to revise and extend results about stability and stabilization of a retarded quasipolynomial and systems obtained using the Mikhaylov criterion in our papers earlier. Not only retarded linear time-invariant time-delay systems (LTI-TDS) are considered in this paper; neutral as well as distributeddelay systems are the matter of the research. A LTI-TDS system of ret...
متن کاملThe Nyquist criterion for LTI Time-Delay Systems
This paper extends results about stability and stabilization of a retarded quasipolynomial obtained using the Mikhaylov criterion earlier. Retarded quasipolynomials appear as numerators and denominators of linear time-invariant time-delay systems (LTI-TDS). A LTI-TDS system of retarded type (destitute of distributed delays) is said to be stable if all roots of its characteristic quasipolynomial...
متن کاملComputer algebra methods for the stability analysis of differential systems with commensurate time-delays
This paper is devoted to the study of the stability of linear differential systems with commensurate delays. Within the frequency-domain approach, it is well-known that the asymptotic stability of such systems is ensured by the condition that all the roots of the corresponding quasipolynomial have negative real parts. A classical approach for checking this condition (see [1]) consists in comput...

In this paper, a consistent pattern with the optimal coordinated design of PSS and SSSC controller to improve the damping of low frequency oscillations is shown. In this design, sensing and signal transmission time delays are considered as effectiveness parameters. The design problem has been considered an optimization problem and biogeography-based optimization (BBO) algorithm is used for sear...
متن کاملAnalysis of Infinite Spectra of Time Delay Systems Using Quasipolynomial Root Finder Implemented in Matlab
Two original algorithms for computing the roots of low order quasipolynomials are introduced in the paper. The first algorithm is based on Weyl's construction combined with argument principle rule. The second algorithm is based on quasipolynomial function mapping in the complex plane. Both algorithms provide the approximate positions of the roots located inside a selected region. The accuracy o...
