Control and synchronization of a 4-scroll chaotic system

A three-dimensional continuous autonomous chaotic system with a 4-scroll attractor was recently reported and studied. In this paper, we further investigate the control and synchronization of this chaotic system. By simply adding and adjusting a constant control term, considered as the "controller," the chaotic system can display complex dynamics, with a different form of a 4-scroll attractor in a compound structure. In addition, synchronization between two such chaotic attractors is achieved and realized by both simulation and circuitry.
