Andronov-Hopf Bifurcation for Relay Systems

Моделирование и анализ информационных систем, 2007
We describe the structure of a monodromy matrix of periodic solutions for relay systems that makes it possible to derive the general criterion for the orbital exponential stability of the cycle.

Application of the Filippov Method to PV‐fed DC‐DC converters modeled as hybrid‐DAEs

Engineering Reports, 2020
Summary In this article, a method to study the nonlinear dynamics of a PV‐fed boost converter is developed. The model for the solar panel introduces an algebraic constraint into the system and the resulting mathematical model is a set of hybrid ...

Dimers for type D relativistic Toda model

Journal of High Energy Physics
We construct dimer graphs for type D relativistic Toda models by introducing impurities into the Y 2N,0 square dimer graphs. By properly placing the impurities and changing the canonical variables assigned to the 1-loops on the dimer graph, we perform a “

D-branes in λ-deformations

Journal of High Energy Physics, 2018
We show that the geometric interpretation of D-branes in WZW models as twisted conjugacy classes persists in the λ-deformed theory. We obtain such configurations by demanding that a monodromy matrix constructed from the Lax connection of the λ-deformed ...

Building multi-BTZ black holes through Riemann-Hilbert problem

Journal of High Energy Physics
We construct a recently found class of non-BPS black hole solutions with asymptotically AdS 3 × S 3 × T 4 in type IIB supergravity, consisting of multiple BTZ black holes localized on an S 3, within the group theoretical framework of Breitenlohner and ...

Eigenvectors of Open Bazhanov-Stroganov Quantum Chain

Symmetry, Integrability and Geometry: Methods and Applications, 2006
In this contribution we give an explicit formula for the eigenvectors of Hamiltonians of open Bazhanov-Stroganov quantum chain. The Hamiltonians of this quantum chain is defined by the generation polynomial $A_n(lambda)$ which is upper-left matrix ...

A Time-Domain Asymptotic Approach to Predict Saddle-Node and Period Doubling Bifurcations in Pulse Width Modulated Piecewise Linear Systems

MATEC Web of Conferences, 2014
In this paper closed-form conditions for predicting the boundary of period-doubling (PD) bifurcation or saddle-node (SN) bifurcation in a class of PWM piecewise linear systems are obtained from a time-domain asymptotic approach.

Application of first-order sensitivity analysis to stabilisation of unstable continuous multi-degree-of-freedom parametric periodic systems

Studia Geotechnica et Mechanica
From a practical point of view, the most important feature of a parametric periodic system is the instability phenomenon. Unlike in systems with constant coefficients, in which only points of instability exist, in parametric systems, whole areas of ...
