摘要
构造了一个新的三维连续自治混沌系统,该系统含有3个参数,2个非线性乘积项通过理论推导、数值仿真、Lyapunov指数谱、分岔图研究了系统的基本动力学特性,还利用FPGA技术设计了一个数字电路,实现三维混沌系统,实验结果与仿真结果完全一致。
A three-dimensional continuous autonomous chaotic system was built, and the new system contains two quadratic cross-product term and three system parameters. Through the theoretical analysis, numerical simulation, Lyapunov exponent spectrum, and bifurcation diagrams, the basic dynamic property of the new system was studied. Furthermore, a digital circuit based on FPGA was designed for hardware implementation of the 3D attractors. The system simulations accorded with the experimental results. A new method for digital implementation of a chaotic system was proposed by using FPGA technology.
