【摘要】 由参数自适应控制和变量驱动原理,对于一类离散非线性混沌系统,提出了实现在不同参数情况下混沌同步的一种方法。在参数自适应控制方程中,控制系数可以是同一个混沌系统的相同系统参数状态下或不同系统参数状态下的混沌信号。常见的参数自适应控制方法中要求控制系数为常量,而在这里可以是变量,甚至是混沌信号,所以,该控制方法更具有普遍性,即常见的参数自适应控制方法是本文方法的一个特例。数值模拟计算表明,此方法对于一类系统是可行的。更多还原

【Abstract】 According to the theory of parameters adaptive control and variable driving, for a kind of discrete nonlinear chaotic systems, a method of chaotic synchronization is presented for different system parameters. In the equation of parameters adaptive control, control coefficients are chaotic signal. Because control coefficients are constant usually for the former parameters adaptive control, so the parameters adaptive control method is very universal, namely the former parameters adaptive control methods are special examples in our control method. Simulation results show that this method is available.更多还原
