Abstract:

A synchronization problem with the same structure for fractional order Chen chaotic systems with known or unknown parameters is studied in this paper. According to the stability theory of fractional order systems, the feedback controller of the system is designed and proved. An electronic circuit is designed to realize the controller using Multisim. The simulation results demonstrate the effectiveness and realizableness of the proposed method.
