Predictor-Based Event-Triggered Controller for Discrete Systems with Network-Induced Delays

In this paper, a predictor-based event-triggered control strategy for discrete systems with network-induced delays is presented. In order to weaken the effect of delays, a simple predictor is carefully designed. An event-triggered control strategy is utilized to save limited network resources, which is further decreased by changed event-triggered threshold parameter. In order to obtain unknown state variables, a Luenberger observer is employed. The theoretical analysis and the numerical simulation results prove that the proposed method is effective.
