In this paper, the problem of robust adaptive tracking for uncertain discrete-time systems is considered from the slowly varying systems point of view. The class of uncertain discrete-time systems considered is subjected to both ' 1 to ' 1 bounded unstructured uncertainty and external additive bound

โฆ Synopsis
Combining the concept of persistent excitation with hybrid adaptation it is shown that any discrete-time adaptive system can be made robust in the presence of bounded perturbations.

This paper is concerned with the problem of robust control of a class of discrete time systems with parameter uncertainty and unknown nonlinearities. The parameter uncertainty we consider is real time-varying norm-bounded and appears in both the state and output equations. We address the problem of
A robust adaptive regulator is constructed for single-inputlsingle-output discrete time systems modelled by a linear time-varying difference equation that includes an error term to incorporate model errors and/or disturbances. It is assumed that the parameters of the nominal model belong to a known
