“…Therefore, the design of memristor chaotic circuits using FPGA is significant for practical applications. Nowadays, a variety of memristor chaotic systems have been implemented by FPGA [34,[40][41][42][43]-for instance, FPGA realization of a novel 5D hyperchaotic fourwing memristive system [44], FPGA implementation of a memristor-based multi-scroll hyperchaotic system [45], etc.…”

A novel, simple, four-dimensional hyperchaotic memristor circuit consisting of two capacitors, an inductor and a magnetically controlled memristor is designed. Three parameters (a, b, c) are especially set as the research objects of the model through numerical simulation. It is found that the circuit not only exhibits a rich attractor evolution phenomenon, but also has large-scale parameter permission. At the same time, the spectral entropy complexity of the circuit is analyzed, and it is confirmed that the circuit contains a significant amount of dynamical behavior. By setting the internal parameters of the circuit to remain constant, a number of coexisting attractors are found under symmetric initial conditions. Then, the results of the attractor basin further confirm the coexisting attractor behavior and multiple stability. Finally, the simple memristor chaotic circuit is designed by the time-domain method with FPGA technology and the experimental results have the same phase trajectory as the numerical calculation results. Hyperchaos and broad parameter selection mean that the simple memristor model has more complex dynamic behavior, which can be widely used in the future, in areas such as secure communication, intelligent control and memory storage.

In this study, a new 4D hyperchaotic system is developed from the 3D Lü chaotic system. The dynamic characteristics of the proposed hyperchaotic system are analyzed using chaotic attractors, equilibrium point stability, Lyapunov exponents’ spectrum, and bifurcation diagrams. Additionally, a linear feedback control method is employed to design the feedback control of the hyperchaotic system. Then, the new hyperchaotic system is implemented using electronic workbench multisim and embedded hardware STM32, and the experimental results are compared with the numerical simulations, showing consistency between them. Finally, using the principle of cross-XOR operation, the audio encryption of hyperchaotic sequence was implemented on the embedded hardware STM32. The results show that the audio encryption scheme based on the hyperchaotic system is feasible, and the method is simple to implement, has nonlinear characteristics and certain algorithm complexity, which can be applied to audio encryption, image encryption, video encryption, and more.

“…[2][3][4][5][6][7][8] In the past few decades, researchers have been exploring the chaos that can produce complex dynamical behavior, and it is worth mentioning that multi-scroll attractors and coexisting attractors have become a hot topic in nonlinear research. [9][10][11][12][13][14][15][16][17][18][19] The state variable can go through multiple orbital states and jump randomly in different transitions for the multi-scroll attractors. The coexisting attractors can provide multiple optional steady states for the system to respond to different needs, so it is very meaningful to construct multi-scroll systems with abundant coexisting attractors.…”

This article proposes a non-ideal flux-controlled memristor with a bisymmetric sawtooth piecewise function, and a new multi-wing memristive chaotic system (MMCS) based on the memristor is generated. Compared with other existing MMCSs, the most eye-catching point of the proposed MMCS is that the amplitude of the wing will enlarge towards the poles as the number of wings increases. Diverse coexisting attractors are numerically found in the MMCS, including chaos, quasi-period, stable point. The circuits of the proposed memristor and MMCS are designed and the obtained results demonstrate their validity and reliability.
