摘 要: 提出用FPGA技术产生多涡卷超混沌吸引子的新方法。基于数字信号处理技术,对连续混沌系统进行离散化处理和变量比例变换,使离散化后的混沌系统便于FPGA实现。文中以四阶蔡氏超混沌系统为典型实例,给出了用FPGA技术产生多涡卷超混沌吸引子的实验结果。 A new approach for generating multi-scroll hyperchaotic attractors by using FPGA technology is proposed. Based on the principle of digital signal processing, using appropriate discrete processing and variable proportion transformation, the continuous chaotic systems can be converted into discrete chaotic systems, which is appropriate for FPGA processing. In this paper, we take fourth-order Chua's hyperchaotic system as an example and give the experimental results of generating multi-scroll hyperchaotic attractors by using FPGA technology.
