Finite/fixed-time synchronization for complex networks via quantized adaptive control

Abstract

In this paper, a unified theoretical method is presented to implement the finite/fixed-time synchronization control for complex networks with uncertain inner coupling. The quantized controller and the quantized adaptive controller are designed to reduce the control cost and save the channel resources, respectively. By means of the linear matrix inequalities technique, two sufficient conditions are proposed to guarantee that the synchronization error system of the complex networks is finite/fixed-time stable in virtue of the Lyapunov stability theory. Moreover, two types of setting time, which are dependent and independent on the initial values, are given respectively. Finally, the effectiveness of the control strategy is verified by a simulation example. 2020 Mathematics Subject Classification. 94C30.

Quasi-synchronization of fractional-order complex networks with random coupling via quantized control

“…In Ref. [37], Shi et al, through the quantized control method, studied the finite-and fixed-time synchronization problems of complex networks using the theory of linear matrix inequality. In Ref.…”

Fixed-Time Synchronization of Coupled Oscillator Networks with a Pacemaker

“…Additionally, many researchers have focused on synchronization time of complex networks [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. In [ 22 ], Shi and Ma presented a unified theoretical method to obtain the finite/fixed-time synchronization for complex networks with uncertain inner coupling by adopting the quantized controller and the quantized adaptive controller. Aouiti and Assali [ 23 ] obtained novel and effective criteria for achieving the finite-time synchronization.…”
