An Introduction to Control of Chaos for Quasi-Integrable Hamiltonian Systems

Quasi-integrable Hamiltonian systems are of great interest in many research fields of physics and mathematics. In these systems, the phase space has regular and chaotic trajectories. These trajectories depend in part on the magnitude of perturbation that breaks the integrability of the system. The value of the critical perturbation responsible for this transition is a key element in the control of chaos . In this paper, we explore a procedure for the control in quasi-integrable Hamiltonian systems via canonical map. Initially, we present the basic tools for this study: Hamiltonian map, linearization of the map and Chirikov criterion. Subsequently, we investigated the behavior of a wave-particle interaction front perturbation. Finally, we confront with a numerical analytical approach (iteration of the map) results, showing a good agreement.
