摘　　要：借助李雅普诺夫稳定性理论提出了一种自适应混沌同步控制方法.该方法通过构造适当的控制函数,从理论上保证了混沌同步控制的稳定性.MATLAB仿真实现了Lorenz系统和Chen系统的混沌同步以及广义Lorenz系统和广义Chen系统的混沌同步控制.An adaptive synchronization algorithm is proposed and the stability of the algorithm is proved based on Lyapunov stability theory. The chaotic synchronization of Lorenz system and Chen system and that of generalized Lorenz system and generalized Chen system are realized by MATLAB. The simulation results show that not only the same chaotic system with different initial values or different parameters but also two different chaotic systems can be synchronized if the control method is used properly.
