Abstract
The stability robustness problem of discrete-time linear regulators with computational delays under nonlinear / linear time-varying perturbations is considered in this paper. A new sufficient condition is derived for the stability robustness of discrete-time linear regulators with computational delays under nonlinear time-varying. perturbations, and a new sifficient bound is presented for structured linear time-varying perturbations of discrete-time linear regulators with computational delays. An example is given to show numerically that the new structured perturbation bound may provide improved results for elemental perturbations over results based on the structured perturbation bound reported recently for linear time-varying perturbations.
