Nonfragile H-infinity output feedback control of linear systems with an event-triggered scheme against unreliable communication links

This paper studies the event-triggered H-infinity static output feedback control of linear systems with unreliable communication. The unreliable phenomenon between the event-triggering unit and the controller is described by a stochastic variable with Bernoulli random binary distribution. To cast the considered problem in the robust control framework, the event-triggering scheme is presented by a time-delay form. A vertex structure separation strategy is utilized to handle control gain with interval variations, which could alleviate computation burden heavily. Resorting to a division of control gain from Lyapunov variable, a new method for the non-fragile H-infinity controller synthesis is established in the framework of linear matrix inequalities. Simulations are executed to show the validity of the proposed approach. (C) 2018 ISA. Published by Elsevier Ltd. All rights reserved.
