Adaptive \(Q-S\) synchronization of fractional-order chaotic systems with nonidentical structures. (English) Zbl 1291.34020

Summary: This paper investigates the adaptive \(Q-S\) synchronization of the fractional-order chaotic systems with nonidentical structures. Based on the stability of fractional-order systems and adaptive control technique, a general formula for designing the controller and parameters update law is proposed to achieve adaptive \(Q-S\) synchronization between two different chaotic systems with different structures. The effective scheme parameters identification and \(Q-S\)synchronization of chaotic systems can be realized simultaneously. Furthermore, two typical illustrative numerical simulations are given to demonstrate the effectiveness of the proposed scheme, for each case, we design the controller and parameter update laws in detail. The numerical simulations are performed to verify the effectiveness of the theoretical results.
