| Abstract: | A new hyperchaotic system with the real four-winged chaotic attractor has been reported in this paper .The four-winged chaotic system has wider frequency bandwidth ,which is important in the field of secret communication .An analog circuit has been designed to implement the new system ,which shows a good agreement between Matlab numerical simulation and Multisim experimental results .By means of ac-tive control synchronization ,the controller has been designed for synchronizing the four-winged hyper-chaotic system and the hyperchaotic Chen system with different structures .The results of numerical simu-lations are provided to show the effectiveness of the proposed method . |
