通过单驱动变量设计了三维分数阶混沌系统通用的自适应同步控制器.基于参数调制原理,利用单驱动变量分数阶混沌系统的同步,提出了一种新的通用型数字通信方案,对电路进行了仿真,同时搭建了实际硬件电路,结果显示接收信息和发送信息符合完好,验证了本方案的有效性和可行性.

Based on the sliding mode variable structure control theory and the adaptive control technique,a single-state adaptive-feedback controller containing a novel fractional integral sliding surface is developed to synchronize a class of fractional-orderchaotic systems. According to the modulation-parameter principle,using single driving variable for a fractional order chaotic system,a kind of digital communication scheme is presented.The results of the circuit stimulation and the circuit experiment show that the information can be received and sent successfully,which demonstrates the feasibility and the effectiveness of the scheme.
