| Abstract: | This paper presents chaos synchronization between two different hyperchaotic dynamical systems with unknown parameters, i.e. an uncertain hyperchaotic Lorenz system and an uncertain hyperchaotic Liu system. Based on Lyapunov stability theory, an adaptive controller and a parameter estimation law are designed to synchronize the two novel hyperchaotic systems. Numerical simulations illustrate the effectiveness of the proposed theory. |

| Keywords: | hyper chaotic system adaptive synchronization parament estimation |
