| Abstract: | The synchronization of the unified chaotic systems using occasional driving technique is studied. The relation among interim period T, sampling interval 2ε, feedback gain r and the parameter α of the system is thoroughly investigated. Numerical results show that smaller interim period T and properly larger sampling interval 2ε can accelerate the synchronizing pace. Furthermore, for a unified chaotic system in which a is given, we can achieve satisfying synchronizing results as long as T,ε and r are appropriately chosen. As we adopt the occasional driving method, we greatly reduce the control cost. Therefore with this method we can obtain the expecting goals with little control cost. |
