摘要
该文通过将反馈控制与小波变换相结合,对混沌同步系统进行了优化设计。在发送端,将系统的部分信号进行小波变换去掉细节信息后发送,在接收端重构出低频信号,将其与接收端信号的差进行反馈。应用本优化方案可将发送信号压缩后传送,节约系统资源;可滤去发送信号中的高频成分,减小干扰和噪声对同步信号的影响。文中给出了仿真验证结果。
The optimizing design of chaotic synchronization system by combining feedback control with wavelet transformation is presented in this paper. In the transmitter, a part of signals is transformed by wavelet and the detail information is removed. In the receiver, the component with low frequency is reconstructed and discrete feedback is used. Using the optimizing design, transmitting signal is transmitted in compressible way, system resource is saved, the component with high frequency is filtered and the effects of disturbance and noise on synchronization are reduced. The optimizing design is illustrated by numerical simulation experiment.
