Sampled-Data Exponential Synchronization of Complex Dynamical Networks With Time-Varying Coupling Delay
TLDR
A criterion is derived to ensure the exponential stability of the error dynamics, which fully utilizes the available information about the actual sampling pattern, and the design method of the desired sampled-data controllers is proposed to make the CDNs exponentially synchronized and obtain a lower-bound estimation of the largest sampling interval.Abstract:
This paper studies the problem of sampled-data exponential synchronization of complex dynamical networks (CDNs) with time-varying coupling delay and uncertain sampling. By combining the time-dependent Lyapunov functional approach and convex combination technique, a criterion is derived to ensure the exponential stability of the error dynamics, which fully utilizes the available information about the actual sampling pattern. Based on the derived condition, the design method of the desired sampled-data controllers is proposed to make the CDNs exponentially synchronized and obtain a lower-bound estimation of the largest sampling interval. Simulation examples demonstrate that the presented method can significantly reduce the conservatism of the existing results, and lead to wider applications.read more

TL;DR: This paper proposes a new Lyapunov function, which is continuous and does not include any sign function, and hence, the chattering phenomenon in most of the existing results is overcome and an optimal algorithm is proposed for the estimation of the settling time.

Nonfragile Exponential Synchronization of Delayed Complex Dynamical Networks With Memory Sampled-Data Control
TL;DR: The sampled-data feedback control, which is assumed to allow norm-bounded uncertainty and involves a constant signal transmission delay, is constructed for the first time in this paper, and a sufficient condition is developed, such that the nonfragile exponential stability of the error system is guaranteed.

TL;DR: A new approach to robust sampled- data control is introduced, modelled as a continuous-time one, where the control input has a piecewise-continuous delay, and sufficient linear matrix inequalities conditions for sampled-data state-feedback stabilization of such systems are derived via descriptor approach to time-delay systems.
