| 摘 要： | 拓展统一混沌系统的非线性函数,构建包含6类子系统的切换统一混沌系统族,不仅每个子类系统在参量空间随系统参数的变化实现切换,而且6类子系统在状态空间随系统非线性函数的变化实现连续切换.利用Lyapunov指数谱和分岔图对6类子系统随系统参数变化的整体情况进行分析,用数字信号处理(DSP)芯片对典型混沌系统的分时切换进行硬件实现.

| Abstract: | A nonlinear function of unified chaotic system, the family of switched unified chaotic system is generated which contains six kinds of subsystems. Each subsystem can be switched by changing systematic parameter values in parameter space, and these subsystems can be switched continuously from one to another via changing nonlinear function in state space. The features of these subsystems are analyzed in detail using Lyapunov exponent and bifurcation diagram. The division-time switching of unified chaotic system is realized based on digital signal processing (DSP). |
