Output tracking-based H∞ control of networked control systems with packet disordering

This paper is concerned with H_∞ output tracking control of networked control systems with packet disordering. Considering random and bounded delay and packet disordering, a mathematical model of networked control systems is proposed by introducing the receive index notion. Output tracking-based H_∞ controller design method is presented in terms of linear matrix inequality (LMI) technology, which is the merit in this paper. The designed controller can guarantee asymptotic tracking of prescribed reference outputs while rejecting disturbances. The simulation results are given to illustrate the effectiveness of the proposed method.
