Robust synchronization of fractional-order unified chaotic systems via linear control.(English)Zbl 1238.93045

Summary: A new scheme for accomplishing synchronization between two fractional-order unified chaotic systems is proposed. The scheme does not require that the nonlinear dynamics of the synchronization error system must be eliminated. Moreover, the parameter of the systems does not have to be known. A controller is a linear feedback controller, which is simple in implementation. It is designed based on an LMI condition. The LMI condition guarantees that the synchronization between the slave system and the master system is achieved. Numerical simulations are performed to demonstrate the effectiveness of the proposed scheme.
