Dynamic event-triggered predictive control for DoS attacks-based discrete-time networked linear systems

Abstract

This paper studies a novel method of the dynamic event-triggered mechanisms and the predictive control scheme for discrete-time networked linear systems subject to network delays and DoS attacks in both sensor-to-controller ([Formula: see text]) and controller-to-actuator ([Formula: see text]) channels. First, by assuming maximum allowable duration of DoS attacks, predictive control scheme is used to proactively offset the adverse impacts of communication constraints. Second, to further save communication resources, dynamic event-triggered mechanisms are configured on sensor and controller sides, respectively. Next, sufficient condition is derived for discrete-time networked linear systems under predictive control and dynamic event-triggered mechanisms, which guarantees the resulting closed-loop system’s asymptotical stability. Finally, a simulation example is used to confirm the availability and applicability of the proposed method.
