Abstract
An alternative approach to analyze the robustness of adaptive systems with respect to unmodeled dynamics and external disturbances is presented. This approach shows that certain restrictive assumptions needed earlier can in fact be discarded. It also shows that an adaptation algorithm based on a time-varying σ-factor, equivalent to a constant σ-factor together with projection, can provide a globally asymptotically stable system with respect to a compact residual set, under mild requirements
