    Input-to-state stabilization for nonlinear sampled-data systems via approximate discrete-time plant models
    Nesic, D ; Laila, DS (IEEE, 2001)
    We provide a framework for the design of L∞ stabilizing controllers via approximate discrete-time models for sampled-data nonlinear systems with disturbances. In particular, we present sufficient conditions that guarantee that a discrete-time controller that input-to-state stabilizes an approximate discrete-time model of a nonlinear continuous-time plant with disturbances would also input-to-state stabilize (in an appropriate sense) the exact discrete-time plant model.

    A note on preservation of dissipation inequalities under sampling: the dynamic feedback case
    Laila, DS ; Nesic, D (IEEE, 2001)
    We present a general and unified framework for the design of nonlinear digital controllers using the emulation method for nonlinear systems with disturbances. Several results on preservation of general dissipation inequalities under sampling are presented. We consider general dynamic feedback controllers case, which generalizes results for static controllers in [8].
