摘要
基于经典Chua混沌电路设计了一个五维双磁控忆阻器混沌电路。对电路非线性特性进行数值分析,表明其具有丰富的混沌动力学行为。采用一阶离散处理对电路进行数字化转换,基于DSP Builder和FPGA(Field Programmable Gate Array)技术,通过CycloneⅣE系列EP4CE10F17C8N芯片搭建的硬件平台,真实实现了该模型数字化系统。设计结果表明,数字化忆阻器系统避免了模拟信号元器件的漂移和不稳定性,硬件波形显示性能稳定可靠,且与计算机仿真结果具有相当一致性的吻合。
Based on the classical Chua’s chaotic circuit,a 5-Dimentional and dual flux-controlled memristive chaotic circuit system is designed.The nonlinear characteristics of the circuit are analyzed numerically and the results show that the circuit has rich chaotic dynamical behavior.The novel memristive continuous system is transformed into digital system by first-order discrete processing.Based on DSP Builder and FPGA technology,a hardware platform of CycloneⅣE series EP4 CE10 F17 C8 N chip realizes the digital system of the model.The design results indicate that the digital memristive system avoids the drift and instability of analog components,the display performance of the hardware waveform is stable and reliable,and is consistent with the computer simulation result.
