Baras, John S.Patel, N.S.In this paper, we construct the information state for robust output feedback control of set-valued discrete time dynamical systems. The information state is obtained as the small noise limit of an appropriate risk-sensitive stochastic control problem. It is possible to obtain this limit by an extension of the Vardgan-Laplace lemma. Finally, the relationship between the information state, and the indicator function of feasible sets is examined.en-USnonlinear systemsrobust controlstochastic systemsSystems Integration MethodologyTechnical Report
