摘要：

This paper is involved with the adaptive control and synchronization problems for an uncertain new hyperchaotic Lorenz system. Based on the Lyapunov stability theory,the adaptive control law is derived such that the trajectory of hyperchaotic Lorenz system with unknown parameters can be globally stabilized to an unstable equilibrium point of the uncontrolled system. Furthermore,an adaptive control approach is presented to the synchronizations between two identical hyperchaotic systems,particularly between two different uncertain hyperchaotic systems. Numerical simulations show the effectiveness of the presented method.
