Abstract :
In this paper, the synchronization and parameter identification of hyperchaotic Lorenz systems are investigated. Based on the finite-time stability theory, nonlinear controllers and parameter identifiers are contrived simultaneously to achieve complete synchronization and parameter identification of the hyperchaotic Lorenz systems in the limited time . The scheme is simple to be implemented in practice. Simulation results are presented to demonstrate that the proposed controllers and identifiers are feasible and effective.
