Synchronization of 4d Rabinovich Hyperchaotic Systems for Secure Communication by K. S. Ojo and S.T. Ogunjo. Vol 21,Pg 35 - 40
Sale price: $5.00


In this article, we investigate the synchronization of two identical four dimensional Rabinovich hyperchaotic systems evolving from different initial conditions.  The active control technique is used to design control variables which enable the states variables of the two hyperchaotic systems to globally asymptotically achieve synchronization. The results show that the error state variables move hyperchaotically with time when the controllers are deactivated for 0<t<80  while, the error converge to zero when the controllers are activated for t≥80.  The system was successfully applied to secure communication using the additive encryption scheme to embed a signal in a component of the system.
