This paper proposes an optimal control solution for the L-2-gain disturbance rejection problem for networked control systems. The problem, usually referred as mixed H-2/H-infinity, aims at designing a linear stabilizing controller minimizing a given cost function subject to a L-2-gain disturbance rejection constraint. The problem is formulated assuming network induced time-varying delays and/or packet losses. An LMI-based minimization problem is derived based on a Lyapunov-Krasovskii approach, considering a polytopic covering of the time-delay range. Simulation results are provided to verify the performance of the methodology.
