【摘要】 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Multisim设计了该系统的模拟电路,其结果与Matlab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.更多还原

【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 active control synchronization,the controller has been designed for synchronizing the four-winged hyperchaotic system and the hyperchaotic Chen system with different structures.The results of numerical simulations are provided to show the effectiveness of the proposed method.更多还原
