Limit or limit superior? Observations on the convergence of some iterative learning control schemes

Abstract

In this paper, we survey the convergence properties of a number of iterative learning control schemes from the past decade. We observe a common technical error that appeared in these papers, point out how the results should be corrected, and finally consider the significance of these corrections with regard to the effectiveness of the schemes concerned. © 2009 Elsevier Ltd.
