Melnikov-type method for a class of planar hybrid piecewise-smooth systems with impulsive effect and noise excitation: heteroclinic orbits
The classical Melnikov method for heteroclinic orbits is extended theoretically to a class of hybrid piecewisesmooth systems with impulsive effect and noise excitation. We assume that the unperturbed system is a piecewise Hamiltonian system with a pair of heteroclinic orbits. The heteroclinic orbit...

| description | The classical Melnikov method for heteroclinic orbits is extended theoretically to a class of hybrid piecewisesmooth systems with impulsive effect and noise excitation. We assume that the unperturbed system is a
piecewise Hamiltonian system with a pair of heteroclinic orbits. The heteroclinic orbit transversally jumps
across the first switching manifold by impulsive effect, and crosses the second switching manifold continuously.
In effect, the trajectory of the corresponding perturbed system crosses the second switching manifold by
applying the reset map describing the impact rule instantaneously. The random Melnikov process of such
systems is then derived by measuring the distance of the perturbed stable and unstable manifolds, the criteria
for the onset of chaos with or without noise excitation is established. In this derivation process, we overcome
the difficulty that the derivation method of the corresponding homoclinic case cannot be directly used due
to the difference between the symmetry of the homoclinic orbit and the asymmetry of the heteroclinic orbit.
Finally, we investigate the complicated dynamics of a particular piecewise-smooth system with and without
noise excitation under the reset maps, impulsive effect, non-autonomous periodic and damping perturbations
by this new extended method and numerical simulations. The numerical results verify the correctness of
the theoretical results, and demonstrate that this extended method is simple and effective for studying the
dynamics of such systems.
