My short paper about asymptotic funnel control (see below) was one of the most downloaded papers of the PAMM in 2019!
Asymptotic tracking with funnel control Inproceedings
In: PAMM - Proc. Appl. Math. Mech., WILEY-VCH Verlag, 2019, (online).
Funnel control is a strikingly simple control technique to ensure model free practical tracking for quite general nonlinear systems. It has its origin in the adaptive control theory, in particular, it is based on the principle of high gain feedback control. The key idea of funnel control is to chose the feedback gain large when the tracking error approaches the prespecified error tolerance (the funnel boundary). It was long believed that it is a theoretical limitation of funnel control not being able to achieve asymptotic tracking, however, in this contribution it will be shown that this is not the case.
