摘　　要：基于五阶段超混沌电路系统、数字化处理技术,通过对系统的连续时间状态方程进行离散化处理和变量比例变换,用FPGA技术硬件实现超混沌电路系统方程中的混沌吸引子;给出了实现混沌吸引子的FPGA技术,指出了硬件实现的方法,展示了实验结果,可以为高阶混沌电路系统的设计与实现提供了一条切实可行的途径,同时该技术可以应用在混沌保密通信中.Based on the fifth-order hyperchaotic circuit system and the digital processing technology, the chaotic attractors in hyperchaotic circuit system equations using FPGA technology is implemented physically through discretizing the continuous-time state equation and variable scaling. The FPGA technology for realizing chaotic attractors is given and physical implementation method is put forward. The experimental results are showed in this paper. It provides a practical method for design and realization of the high-order chaotic circuit systems. At the same time, the technology can be applied in chaotic encryption communication.
