Abstract

Bifurcations of periodic orbits of three-well Duffing system with a phase shift are investigated in detail. The conditions of the existence and bifurcations for harmonics, subharmonics (2-order, 3-order and m-order) and superharmonics under small perturbations are given by using second-order averaging method and
Melnikov's method. The influence of the phase shift on the dynamics is also obtained.

Key words

Bifurcations / Melnikov's method / periodic orbits / second-order averaging / three-well Duffing system.
