چکیده:

This paper investigates the problem of robust stabilization for uncertain networked control systems (NCSs) with random time delay via the output feedback control. A modedependent controller is proposed by modeling the random delay as a Markov Chain. The resulting closed-loop system is expressed as aMarkovian jump linear system (MJLS) with mode-dependent delay. Based on Lyapunov-Krasovskii method, robust stability conditionand controller design method for such networked control systems with structured uncertainties are presented. The result is formulated in terms of LMIs. Output feedback gain can then bederived by using the feasible solution of LMIs. Simulation example demonstrates the feasibility and effectiveness of the proposed approach.
