一个新的四维混沌系统及其电路实现

A New Four-dimensional Chaotic System and Its Circuitry Implementation

为了产生复杂的混沌吸引子,提出了一个新的四维自治混沌系统,实现了真正的四翼混沌吸引子,通过仿真给出了该系统的时域图和功率谱图,同时设计了该系统的实现电路.试验结果与仿真结论完全一致.电路结构简单,实现容易.对保密通信和信号加密等基于混沌的实际应用有重要意义.

In order to generate complex chaotic attractors,a new four-dimensional chaotic system is built in this paper,which gives birth to a true four-winged chaotic attractor,graph in time domain and power spectrum were drawn,electronic circuit was designed to realize the chaotic system.Experimental chaotic behaviors of the system were found to be identical to the simulations,and it is easy to realize in circuit.The circuit is important to secure communication and practical applications in communication encryption.
