  • 摘要: 讨论一类4D忆阻混沌电路的动力学行为,并研究多稳定性的吸引域.为保证计算结果的高效性和准确性,利用CPU+GPU的大规模计算能力和具有128位小数的多精度GMP库及MPFR库,计算出对应吸引子的吸引域,并用区间牛顿法验证当吸引域很小时吸引子的存在性;最后运用拓扑马蹄理论和构造忆阻模拟电路两种方式验证系统超混沌的存在性.

     

    Abstract: Dynamical behavior of a class of 4D memristive chaotic circuits was discussed, and attracting domain of multi-stability was studied. In order to guarantee efficiency and accuracy of calculation results, CPU+GPU large-scale computing power were introduced and more than 128 decimal places of precision GMP library and MPFR library were applied to calculate domain of corresponding attractor. Finally, existence of hyperchaos was proved by using method of topological horseshoe theory and constructing memristive analog circuit.
