The funnel pre‐compensator

T Berger, T Reis - … Journal of Robust and Nonlinear Control, 2018 - Wiley Online Library
We introduce the funnel pre‐compensator as a novel and simple adaptive pre‐compensator
of “high‐gain type”. We show that this pre‐compensator is feasible for a large class of signal …
