ADAPTIVE SYNCHRONIZATION OF UNCERTAIN RÖSSLER SYSTEM BASED ON PARAMETER IDENTIFICATION

Assuming the Rossler system as a reference, this paper studies two cases of chaotic synchronization of a pair of (master and slave) systems: one with fully uncertain parameters for both, the other where the master system has fixed given parameters while the slave system is endowed with uncertain parameters. The respective adaptive controller based on parameter identification is then designed, according to the Lyapunov stability theorem. Then, it is proved that the two controllers are capable of making the two (identical) Rossler systems asymptotically synchronized. Numerical simulation results further testify the efficiency of controllers.
