Model Quality for the Windsurfer Scheme of Adaptive Control

Abstract

The Windsurfer Approach to adaptive control combines Internal Model Control (IMC) design parametrized by the desired closed-loop bandwidth with event-driven system identification using Hansen’s scheme on closed-loop data. Our aim in this work is to investigate the nature of model quality applicable to the windsurfer approach. We do this by expanding on recent activities dealing with the complete class of all models suited to model reference control design. In particular, we interpret the conditions for simultaneous stabilization of the plant and the model by an IMC controller. This extends the model reference results to a different domain in which the controller is characterized algebraically by the model but also inherently includes a specification of design performance objective.
