A generalized Van del Pol oscillator with slowly varying parameter is studied. The leading order approximate solutions are obtained respectively by three methods and comparisons are made with numerical results. Different amplitudes are also made to compare the accuracy of the three methods.

A Linear Approach to the Control of Vortex Induced Vibrations of Circular Cylinders with a 2-D Van der Pol Model for Structural Oscillator
In the present paper, a new 2-D Van der Polstructural oscillator model is introduced for the vortex induced vibrations of circular cylinders.The main purpose of this task is to control the recently introduced model by means of modern control definitions in state space. In order to control the system, the whole model is linearized about its equilibrium point by deriving state-space matrices. The...
متن کاملAsymptotic Stability of Periodic Solutions for Nonsmooth Differential Equations with Application to the Nonsmooth van der Pol Oscillator
In this paper we study the existence, uniqueness and asymptotic stability of the periodic solutions of the Lipschitz system ẋ = εg(t, x, ε), where ε > 0 is small. Our results extend the classical second Bogoliubov’s theorem for the existence of stable periodic solutions to nonsmooth differential systems. As application we prove the existence of asymptotically stable 2π–periodic solutions of the...
متن کاملQuasiperiodic phenomena in the Van der Pol - Mathieu equation
The Van der Pol Mathieu equation, combining self-excitation and parametric excitation, is analysed near and at 1 : 2 resonance, using the averaging method. We analytically prove the existence of stable and unstable periodic solutions near the parametric resonance frequency. Above a certain detuning threshold, quasiperiodic solutions arise with basic periods of order 1 and order 1/ε where ε is t...
متن کاملEstimation of slowly varying parameters in nonlinear systems via symbolic dynamic filtering
This paper introduces a novel method for real-time estimation of slowly varying parameters in nonlinear dynamical systems. The core concept is built upon the principles of symbolic dynamic filtering (SDF) that has been reported in literature for anomaly detection in complex systems. In this method, relevant system outputs are measured, at different values of a critical system parameter, to gene...
متن کاملGeneralized geometric phase of a classical oscillator
The equation of a linear oscillator with adiabatically varying eigenfrequency ω(εt) (ε 1 is the adiabaticity parameter) is considered. The asymptotic solutions to the equation have been obtained to terms of order ε3. It is shown that imaginary terms of order ε2 form a generalized geometric phase determined by the geometry of the system’s contour in the plane (ω, ω′). The real terms of orders ε ...
