Abstract

Most adaptive control algorithms make little or no connection with the frequency domain concepts so crucial to an understanding of classical control. We outline how frequency domain concepts can influence the design of adaptive algorithms. These influences arise in two areas: determining the rate of convergence of an adaptive algorithm, and determining the robustness of an algorithm, that is, its ability to function satisfactorily in the presence of departures from the idea, such as undermodelling or failure to model high frequency plant dynamics. The end conclusions from these considerations involve frequency control or external driving signals, use of regression vector filtering, and consideration of frequency bands in which the plant may be difficult to model.
