State feedback control of networked control system with random delay

The problems of system stability and H₂/H_∞ control are discussed by convert the uncertainty of time delays to the uncertainty of system parameters, and the design of state feedback is developed, which is a good solution of the problem of asymptotic stability of closed-loop system. To guarantee robust stability of the system, transfer function T_ωz in the closed system is not in excess of the common upper bound; in a addition, to achieving the better performance of control system token by H₂ norms, H₂ norms of transfer functions T_ωz in the closed system is satisfied with certain conditions. A simulation example illustrate the validity of the design method presented above.
