提出了一个新的具有真正四翼混沌吸引子的超混沌系统，通过频谱分析发现，该四翼混沌吸引子的系统信号具有较宽的带宽，这在保密通信领域具有重要的价值。利用 M ultisim 设计了该系统的模拟电路，其结果与M atlab数值仿真结论相一致。利用主动控制同步法设计控制器，实现了该四翼超混沌系统和超混沌Chen系统的异结构同步，数值仿真结果验证了该方法的有效性。

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 .
