Abstract
Autoresonance is a phase locking phenomenon occurring in nonlinear oscislatory system, which is forced by oscillating perturbation. Many physical applicatcons of the autoresonance are known in nonlenear physics. The essence of the phenomecon is that the nonlinear oscillator selfadjusts to the varying external conditions so that it remains in resonance with the orivvr for a long time. This long time resonance leads to a strong increase in the response amplitude under weak drivinc perturbation. An analytic treatment of a simple mathematical model is done here by means of asymptotic analysis using a small driving parameter. The main result is finding threshold for entering the autoresonance.
