Bifurcations of periodic solutions and chaos in Josephson system
The Josephson equation is investigated in detail: the existence and bifurcations
for harmonic and subharmonic solutions under small perturbations are
obtained by using second-order averaging method and subharmonic Melnikov function,
and the criterion of existence for chaos is proved by Melnikov analysis; the
bifurcation curves about n-subharmonic and heteroclinic orbits and the driving frequency
$\omega$ effects to the forms of chaotic behaviors are given by numerical simulations.
