Synchronization of hyperchaotic rossler system with uncertain parameters via nonlinear control

Abstract

Based on the Lyapunov stability theory, a new method for synchronization of hyperchaotic Rossler system with uncertain parameters is proposed. By this method, choosing appropriate control law and adaptive update law of uncertain parameters, all the errors of system variable synchronization and of uncertain parameter track are asymptotically stable. The theoretical analysis and the numerical simulations prove the effectiveness of the proposed method.
