Abstract: |
This chapter discusses the behavior of non-autonomous dynamical systems through simple models (conservative or with damping) of nonlinear oscillators with external periodic forcing. Oscillations are qualitatively classified and distinguished using the Poincare stroboscopic map. Homoclinic chaos in the conservative case and strange attractors in the case of damped oscillations are presented. Specifically, the following topics are addressed:
Linear oscillators without damping with periodic forcing
The stroboscopic map or Poincare map
Typical periodic oscillations (subharmonic, etc.)
Nonlinear conservative systems with periodic forcing
Phase space with the Poincare map
Homoclinic chaos
The Duffing oscillator - Limit cycles and strange attractors
The perturbed pendulum
Exercises and computational problems
