MIMO CHANNEL COMMUNICATION-BASED H∞ CONTROL OF WIRELESS NETWORKED CONTROL SYSTEMS

摘要

This paper investigates the optimal control scheme for wireless networked control systems over multi-input and multi-output (MIMO) channel communication. With the introduction of concept of packet displacement, a mathematical model is constructed to fully describe the real-time dynastic characteristic of MIMO wireless network, such as packet disordering. It is worthwhile mentioned that the resulting closed-loop systems are jump linear systems due to the newest signals executed subject to Markovian chains, based on which an adaptive and optimal controller is designed such that optimal H∞ norm bound is obtained in terms of Markovian theory combined with linear matrix inequality (LMI) techniques. Finally, experimental simulations are carried out to illustrate the effectiveness of the proposed method.
