摘要
对混沌同步方法进行了研究,利用参量驱动法实现了两个混沌系统的同步.以Bragg声光双稳系统为例进行仿真模拟,验证了这种方法的有效性.仿真模拟结果表明:当外加驱动信号作用于两系统的某个被驱动参量,两个初始条件不同的Bragg声光双稳系统误差变量很快平稳地趋于零,说明该同步方法是快速有效的.
Chaos Synchronization method was studied. A parameter driven method was used to realize chaos synchronization. Bragg acousto - optic bistable systems were taken as examples to verify the effectiveness of the method. Simulation results show that when an external signal is added on driven parameters of the two systems,the error variables of the two Bragg acousto optic bistable systems with different initials approach zero smoothly and rapidly in a short series of time, which shows the method is effective and practical.
