H∞ Control of Network Control System for Singular Plant

Abstract

This paper investigates H∞ control method for a class of singular network control systems (SNCS) based on singular plant. Considering the network delay, external disturbance, impulse behavior and structural instability of singular plant, the H∞ control of SNCS with state feedback and dynamic output feedback are investigated respectively by approach of linear matrix inequality (LMI). The existence H_∞ control law, the solving H_∞ control law and disturbance degree are presented respectively. Simulation results illustrate the effectiveness and feasibility of the given approach.
