Constructive robustness analysis of a limited-information feedback approach for nonlinear systems

We analyze the robustness properties of a recently introduced strategy for stabilization with limited information. We show that if the nominal closed-loop system can be made Input-to-State Stable (ISS) with respect to measurement errors, parameter uncertainty and exogenous disturbances then this robustness is preserved when only limited information is available on the plant. More precisely, if a sufficiently bandwidth is available on the communication network, then the resulting closed-loop is semiglobally practically ISS.
