Localized hamiltonian control theory gives the possibility to reduce the radial chaotic transport of plasma test-particles into the Tokamak, by creating the Internal Transport Barrier(ITB). We prove that the control term is of quadratic order in the perturbation of Hamiltonian. We apply this method to a phenomenological model of electric potential in magnetized plasma.
