Abstract

We present a technique to control chaos in Hamiltonian systems which are close to integral. By adding a small and simple control term to the perturbation, the system becomes more regular than the original one. We apply this technique to a model that reproduces turbulent E × B drift and show numerically that the control is able to drastically reduce chaotic transport.
