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.
Adaptive control is applied to a particular class of SISO discrete-time non-linear systems. Global boundedness and convergence are obtained by introducing a modification to a classical adaptive scheme.
This paper deals with adaptive control based on explicit identification. The problem of admissibility of the identified model is solved without requiring persistently exciting inputs. This solution is robust with respect to process variations, unstructured disturbances and model order errors. Finall
