研究了一种基于广义函数投影滞后同步的保密通信方案。广义函数投影滞后同步指的是驱动系统的输出滞后于响应系统,同时两者的输出信号比值是一个确定的函数比例矩阵。首先提出一种基于超混沌系统广义函数滞后同步的保密通信方案,在发送端,有用信号被调制到Iorenz-Stenflo(LS)系统的第四个状态变量上。基于自适应控制方法,设计了相应的控制器,使得Lorenz-Stenflo(LS)和Lu超混沌系统渐进同步。最后,有用信号可以从输出端提取出来。数值仿真验证了该方案的有效性。 A secure communication scheme based on the delay of projection of generalized functions is studied. The generalized function projection hysteresis synchronization refers to the output of the drive system lagging behind the response system, and the ratio of the output signals of the two is a certain function matrix. First, a secure communication scheme based on the lag synchronization of the generalized function of the hyperchaotic system is proposed. At the transmitting end, the useful signal is modulated onto the fourth state variable of the Iorenz-Stenflo (LS) system. Based on the adaptive control method, a corresponding controller is designed to make Lorenz-Stenflo (LS) and Lu hyperchaotic systems asymptotically synchronized. Finally, the useful signal can be extracted from the output. Numerical simulation verifies the effectiveness of this scheme.
