Abstract:

This paper studies the model reference output tracking problem for stochastic networkbased control systems with a single delay and parameter uncertainties residing in a polytope. Attention is focused on the design of controller, which guarantees that the stability of systems and a prespecified L2L∞ performance γ 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 L2L∞ output tracking design scheme.
