.Synchronization of hyperchaotic rossler system with uncertain parameters via nonlinear control[J].Optoelectronics Letters,2006,2(5):389-391 Synchronization of hyperchaotic rossler system with uncertain parameters via nonlinear control DONG En-zeng CHEN Zeng-qiang YUAN Zhu-zhi Department of Automation, Nankai University, Tianjin 300077, China 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 param- eter track are asymptotically stable. The theoretical analysis and the numerical simulations prove the efffectiveness of the oroDosed method. Hits: 3704 Download times: 174 View Full Text    Download reader
