On stabilization of nonlinear systems under data rate constraints using output measurements

We present a contribution to the problem of semi‐global asymptotic stabilization of nonlinear continuous‐time systems under data rate constraints when only output measurements are available. We consider systems which are uniformly observable and we point out that the design of an ‘embedded‐observer’ decoder and a controller which semi‐globally stabilize this class of systems under data‐rate constraints requires an appropriate choice of the observer gain and the data rate.
