Abstract: This paper investigates the problem of H∞ output tracking for stochastic network-based control system. Attention is focused on the design of controller, which guarantees the stability of systems and a prespecified H∞ performance for the stochastic network-based control systems with respect to all energy-bounded input signals. Sufficient conditions are proposed in terms of linear matrix inequality, and the corresponding controller design is cast into a convex optimization problem. A numerical example illustrates the effectiveness of the proposed H∞ output tracking design scheme.
