In this paper,the design problem of H-infinity robust control is investigated for networked sys-tems with access constraints and packet dropout.Firstly,the Bernoulli random process is utilized to de-scribe the packet loss process of the networked system,and a discrete-time Markov jump system model is established according to the random-access mechanism of medium access constraints.Secondly,sufficient conditions for stochastic stability of the closed-loop system are derived by using Lyapunov stability theory and LMI technology.Correspondingly,H-infinity robust controller is designed to render the closed-loop system stochastic stability with the given H-infinity performance.Finally,an example is given to verify the correctness and effectiveness of the proposed control method.
