Generalized quantized intermittent control with adaptive strategy on finite-time synchronization of delayed coupled systems and applications

Abstract

This paper is concerned with the finite-time synchronization problem of coupled drive-response systems with time-varying delays via quantized adaptive aperiodically intermittent control. Compared with previous research results, the intermittent control is aperiodic and coupling functions are nonlinear. Furthermore, both internal time-varying delays and coupling time-varying delays are considered. By employing Lyapunov–Krasovskii functional method and Kirchhoff’s Matrix Tree Theorem, some novel sufficient conditions are derived to guarantee that drive-response systems can achieve synchronization in finite time. Specially, the convergence time is discussed. It is worth pointing out that the convergence time is closely related to topological structure of networks and the maximum ratio of the rest width to the aperiodical time span. Finally, finite-time synchronization of a typical second-order Kuramoto model with time-varying delays and Chua’s circuits model with time-varying delays are studied by using our theoretical results. Meanwhile, the numerical simulations are given to illustrate the effectiveness of the theoretical results we obtained.
