SINGULAR PERTURBATIONS FOR THE FORCED VAN DER POL OSCILLATOR
Main Article Content
Abstract
This paper deals with the Van der Pol oscillator with large si nusoidal forcing term. By using singular perturbation techniques a.symp totic solutions of such a system are constructed. We considered the case $b$ small and then we find the range of values of $b$ for which the Van der Pol oscillatore may have 3 stable subharmonic solutions for the same values of the parameters. We have integrated the equation numerically; then a comparison of the numerical results obtained with analytical results of this paper is given.
