Abstract: This paper introduces a switched hyperchaotic system that converts its states from one subsystem to another via two switch functions. The basic dynamic characteristics, such as symmetry, dissipation, equilibrium, stability, bifurcation diagram and Lyapunov exponent spectrum of this system are analyzed. The system is implemented by FPGA hardware. It is shown that the experimental results are identical with numerical simulations.

Key words: hyperchaos, switch function, Field Programmable Gateway Array(FPGA) hardware implementation, bifurcation

摘要： 提出一个开关超混沌系统，通过2个开关函数控制不同超混沌子系统之间的切换。分析开关超混沌系统的对称性、耗散性、平衡点、稳定性、分岔图和Lyapunov指数图等动力学特性。采用FPGA技术对该系统进行硬件实现，其电路实验结果与数值仿真结果相同。
