✦ Synopsis
It is shown that uniform global exponential stability of the input-free discrete-time model of a globally Lipschitz sampled-data time-varying nonlinear system with inputs implies ÿnite gain Lp stability of the sampled-data system for all p ∈ [1; ∞]. This result generalizes results on Lp stability of sampled-data linear systems and it is an important tool for analysis of robustness of sampled-data nonlinear systems with inputs.

The fundamental Luenberger observer for continuous systems can be extended to stabilize linear, and also a class of nonlinear, sampled-data systems by an algorithmic procedure which determines observer constants and feedback gains.
A su~cient condition for absolute stability in the bounded-input-bounded-output sense for a class of nonlinear sampled-data systems is obtained. The stability theorem yields a Popov-type frequency domain test on the linear plant. The obtained criterion is identical to the criterion that establishes
This paper describes a graphical evaluation of the robust stability in a frequency domain based on the results from our previous paper in which the extension of Popov's criterion to discrete-time systems was expressed in an explicit form. The control system described herein is a sampled-data control
