Aimed at modified unfied system,this paper,based on Lyapunov stability theory,proposes a scheme for accomplishing the C-A synchronization and anti-synchronization of chaotic modifeid unfied system by using tracking control method and designing a better controller for controlled system.

Adaptive synchronization control for unified chaos systems;

The design method of synchronization control of unified chaos systems is considered and three kinds of exponential terminal hyper-surface is proposed which can drive the system state variables into the equilibrium point no matter the initial states is far away or near the equilibrium point in a fast finite time.
