A note on convergence property of iterative learning controller with respect to sup norm
Hak-Sung Lee,Zeungnam Bien +1 more
TL;DR: It is reported that huge overshoot may be observed in the output trajectory error, even though the applied learning algorithm has been proved to be exponentially convergent with respect to the λ-norm.

Design Issues on Robustness and Convergence of Iterative Learning Controller
Hak-Sung Lee,Zeungnam Bien +1 more
TL;DR: The results show that the pure error term in PD-type learning law is closely related to the two issues of robustness to the initial error and the convergence in the sense of sup-norm.
