Output-feedback design of networked control systems and estimating maximum data packets dropout

This paper considers networked control systems (NCS) with data packet dropout, NCS with data packet dropout is equivalent to a continuous time-delay system. Based on Lyapunov-Krasovskii stability theory, a new condition for stabilization of the closed-loop system by output-feedback is presented. Moreover, by using the method of free weights matrix and parameter adjusting, LMI criterion of computing maximum data packets dropout is obtained. In accordance with the criterion, convex optimal condition is obtained, then data packets dropout of the system is estimated. Finally, a simulation experiment illustrates the effectiveness of the proposed method.
