Combination event-triggered adaptive networked synchronization communication for nonlinear uncertain fractional-order chaotic systems

摘要

In this paper, the networked synchronization communication for nonlinear uncertain fractional-order chaotic systems is investigated. Notice that the network transmission capacity is limited, a novel combination event-triggered mechanism is designed. Based on the fractional Lyapunov stability criterion and adaptive control technique, an event-triggered adaptive controller is constructed and a sufficient networked synchronization condition for the above-mentioned fractional-order chaotic systems with uncertainties and disturbances is attained. The detailed theoretical derivation and specific numerical simulation demonstrate that the proposed networked synchronization strategy can reduce the burden of network bandwidth effectively without losing the desired synchronization performance. Meanwhile, Zeno phenomenon is excluded. (C) 2018 Elsevier Inc. All rights reserved.
