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

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.
7'his work is a generalization of Tsypkin's stability criterion for a class of time-varying nonlinear sampled-data feedback systems. Some sufficient conditions for the response to any bounded input sequence to be bounded are preserded. No assumptions are made concerning the internal dynamics of the
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 ΓΏnite gain Lp stability of the sampled-data system for all p β [1; β].
