Synchronization of identical and non-identical 4-D chaotic systems using active control

This paper presents chaos synchronization between two identical Lorenz–Stenflo (LS) and a new four-dimensional chaotic system (Qi systems) by using active control technique. The designed controller ensures that the state variables of the controlled chaotic slave LS and Qi systems globally synchronizes with the state variables of the master systems respectively. It is also shown that Qi system globally synchronizes with LS system under the generalized active control. The results are validated using numerical simulations.
