H_∞ Control for Networked Systems with Random Time Delay and Data Packet Dropout

Abstract:

This paper studies the H∞ control problem of networked control systems (NCSs) with random time delay and packet dropout, respectively, for the case that system state is unavailable. The output feedback closed-loop NCS is modeled as a discrete-time switched system. A necessary and sufficient condition is derived for the NCSs ' asymptotic stability based on robust stability techniques, under which the system is exponential stability with a desired H-infinity disturbance attenuation level. The designed output feedback based H∞ controller is obtained by solving a set of linear matrix inequalities. The result illustrate that the effectiveness of the proposed control design and the satisfactory performance of the system.
