Features of dynamic processes in the “indentor – coating” system during tests on a tribometer

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2023
The features of a nonlinear model of the indenter-coating tribosystem of a tribometer are considered. It is shown that with an increase in the amplitude of harmonic perturbation, the dynamic system goes through the stage of doubling the cycle and passes ...

Equivalent dimensionality reduction method of doubly‐fed induction generator model and discrimination of Hopf bifurcation type

open access: yesEnergy Science & Engineering, 2023
The strong coupling, multivariate, and nonlinear characteristics of the mathematical model of a doubly‐fed induction generator (DFIG) make it challenging to analyze the bifurcation category of the DFIG. Therefore, in this study, we developed a method for

Stability Analysis of Equilibrium Point and Limit Cycle of Two-Dimensional Nonlinear Dynamical Systems—A Tutorial

open access: yesApplied Sciences, 2023
The equilibrium state of a dynamical system can be divided into the equilibrium point and limit cycle. In this paper, the stability analysis of the equilibrium point and limit cycle of dynamical systems are presented through different and all possible ...

Simultaneous occurrence of sliding and crossing limit cycles in piecewise linear planar vector fields [PDF]

open access: yes, 2019
In the present study we consider planar piecewise linear vector fields with two zones separated by the straight line $x=0$. Our goal is to study the existence of simultaneous crossing and sliding limit cycles for such a class of vector fields.

Limit Cycles and Integrability of a Class of Quintic System

open access: yesMathematics, 2022
In this paper, a class of quintic systems is investigated. The first 13 focal values are computed with the aid of MATHEMATICA. Then the necessary conditions of integrability and linearizability are obtained and the sufficiency of every condition is ...

Characteristics of the Limit Cycle of a Reciprocating Quantum Heat Engine [PDF]

open access: yes, 2004
When a reciprocating heat engine is started it eventually settles to a stable mode of operation. The approach of a first principle quantum heat engine toward this stable limit cycle is studied.

Bifurcation Analysis of a Stochastically Driven Limit Cycle [PDF]

open access: yes, 2018
We establish the existence of a bifurcation from an attractive random equilibrium to shear-induced chaos for a stochastically driven limit cycle, indicated by a change of sign of the first Lyapunov exponent.

Reproducibility of a noisy limit-cycle oscillator induced by a fluctuating input [PDF]

open access: yes, 2006
Reproducibility of a noisy limit-cycle oscillator driven by a random piecewise constant signal is analyzed. By reducing the model to random phase maps, it is shown that the reproducibility of the limit cycle generally improves when the phase maps are ...
