Adaptive synchronization of a hyperchaotic Lü system based on extended passive control

doi:10.1088/1674-1056/19/6/060505

Abstract This paper investigates the adaptive synchronization of hyperchaotic Lü systems based on the method of extended passive control. By combining the feedback control, the extended passive control method with two output variables is developed, which can synchronize hyperchaotic Lü systems asymptotically and globally more easily without knowing the bound of state of the hyperchaotic system. Adaptive laws are introduced to estimate the unknown parameters as well. Simulation results show the effectiveness and flexibility of the proposed control scheme.

Keywords: hyperchaotic Lü system synchronization extended passive control adaptive control
