Abstract

The adaptive synchronization of unified chaotic system is studied when the parameter of drive system is unknown and the parameter of response system is adjustable. Based on Lyapunov stability theory and combining driving method, two new adaptive control methods for the synchronization of unified chaotic system are presented by employing multiple controllers and only a single controller. The analytical expression of synchronization controllers and adaptive law of parameter are given. Numerical simulations show the effectiveness and feasibility of the two developed methods.
