  • Abstract
    Some results on robustness to unmodeled dynamics of adaptive controllers using normalization factors are analyzed. It is shown that the proofs given by various authors fail to establish that the proposed adaptive controllers provide a nonvanishing robustness margin for the class of unmodeled dynamics considered.<>
