Finite-time H∞ control of uncertain networked control systems with randomly varying communication delays

This paper is concerned with the problem of finite-time H-infinity stability analysis of uncertain discrete-time Networked Control Systems (NCSs) with varying communication delays in a random fashion. Both measurement and actuation delays are modeled by two independent Bernoulli distributed white sequences. A dynamic output feedback controller is designed to realize finite time control for this class of NCSs with prescribed H-infinity performance level. An iterative algorithm is developed to compute the controller's parameters by means of the Cone Complementarity Linearization Method (CCLM). The validity and feasibility of the proposed stability criterion are confirmed via numerical simulation examples. (C) 2017 ISA. Published by Elsevier Ltd. All rights reserved.
