| 摘 要： | 针对一类参数未知的不确定混沌系统,将自适应方法与非线性反馈方法相结合,实现了异结构混沌系统的自适应同步控制.基于Lyapunov稳定性理论,设计了自适应控制器和参数自适应律.采用所设计的自适应控制器和参数自适应律,在一定的条件下,可以实现参数不确定异结构整数阶混沌系统的大范围渐近同步.为了减小控制所需的能量,对控制系数k0引入自适应估计,优化控制系数.计算机仿真结果进一步验证了所设计方法的有效性和可行性.

| Abstract: | For a class of uncertain chaotic systems with unknown parameters,the adaptive synchronization control of two different chaotic systems is achieved in the paper,by means of the adaptive approach combined with the nonlinear feedback method.First,based on the Lyapunov stability theory,the adaptive controller and the parameter identification scheme are presented.Second,under certain conditions,large-scale asymptotic synchronization is proposed between two different uncertain integer order chaotic systems.Third,... |
