Chaotic chameleon: Dynamic analyses, circuit implementation, FPGA design and fractional-order form with basic analyses

摘要

Highlights ? This paper introduces a chamelon chaotic system which can change between hidden attractor and self-excited attractor depending on the value of parameter. ? The complex dynamic behaviors of the system are revealed by analyzing the corresponding equilibria and using the numerical simulation method. ? The electronic circuit application and FPGA-based oscillatorare realized for implementing the chaotic chamelon attractors of the system as real-time applications. ? The fractional-order form of chamelon chaotic system is derived from original system. Also, the FPGA-based application and some analyses are done such as bifurcation and stability for fractional-order form. 展开▼
