提出了采用一个控制器自适应同步参数全部未知的Lü混沌系统的方法.基于Lyapunov稳定理论,设计了单一控制器和参数自适应律,它改进和完善了Elabbasy等人采用三个控制器[8]及Han等人采用二个控制器[9]的工作.数值仿真结果验证了该方法的有效性和可行性.“,”An adaptive control method for the synchronization of Lü system with fully unknown parameters is presented by employing only a single controller. The single controller and adaptive laws of parameters were designed based on Lyapunov stability theory. The obtained results here improved and extended the works of Elabbasy et al. with three controllers [8] and Han et al. with two controllers [9]Numerical simulations are provided to show the effectiveness and feasibility of the developed method.
