In this talk, we revise a series of recent advances on the challenging problem of robust periodic output regulation, that is, the problem of tracking periodic references
(and/or rejection periodic disturbances) for nonlinear systems, robustly with respect to model uncertainties. This problem is well understood in the context of linear systems thanks
to the celebrated "internal-model principle" established during the 70's. But, for nonlinear systems, it is still open. This work aims at clarifying challenging and possible solutions,
connecting the theory of repetitive control with output regulation by means of infinite-dimensional dynamic regulators. In this context, a strong connection between the output regulation
problem and the theory of repetitive control is established. Finally, we propose a new feedback design for a repetitive control scheme for minimum-phase nonlinear systems.
Such a scheme is based on the forwarding approach and allows to deal with systems with high-order relative degree between the input and the regulated output.
Daniele Astolfi received a joint Ph.D. degree in Control Theory from the University of Bologna, Italy, and from Mines ParisTech (PSL Research University), France, in 2016.
From 2016 to 2017, he has been a Research Assistant at CRAN, Nancy, France. Since 2018, he is a CNRS Researcher at LAGEPP, Lyon, France.
In 2023 he got his Habilitation to Master the Reasearch (HDR) from University of Lyon.
His research interests include observer design, output regulation and synchronization for nonlinear, PDEs and hybrid systems.
He serves as an associate editor of the IFAC journal Automatica since 2018 and European Journal of Control since 2023 and for several conferences in control (ECC, IFAC WC).
He is also member of the Technical Committees IEEE CSS TCNSC and IFAC TC 2.3 on nonlinear control systems. He was a recipient of the 2016 Best Italian Ph.D.
