A Practical Fixed-Time Intermittent Event-Triggered Control Scheme for Complex Dynamical Networks

What the paper says
This article investigates the practical fixed-time synchronization (FxTS) for complex dynamical networks (CDNs). Given the notable benefits associated with intermittent control, wherein control inputs are activated solely during the working phase of each control cycle, and event-triggered control, which significantly curtails the frequency of control input updates, this article proposes an intermittent event-triggered control scheme aimed at achieving practical FxTS in CDNs. The proposed scheme substantially mitigates the volume of information transmitted across the network while concurrently reducing control-related expenditures. To mitigate the issue of high-frequency buffeting, the newly devised control scheme employs a saturation function as a substitute for the conventional signum function. Subsequently, this article presents a more precise estimation approach for reasonably approximating the synchronization time (ST) of CDNs and the synchronization error (SE) induced by the integration of the saturation function. Moreover, this article imposes constraints on the frequency and total duration of communication pauses in an average-sense manner and constructs a piecewise Lyapunov function to further deduce several less conservative criteria for practical FxTS. Finally, two illustrative examples are provided to demonstrate the viability of the intermittent event-triggered control scheme and the accuracy of the ST and SE estimations.
