Published in 2022 at "IEEE Transactions on Automatic Control"

DOI: 10.1109/tac.2021.3137103

Abstract: This article is concerned with the output-feedback tracking control problem for a class of nonlinear systems. The challenge lies in how to drive the tracking error to a prescribed region in a given time globally,… read more here.

Published in 2020 at "IEEE Transactions on Fuzzy Systems"

DOI: 10.1109/tfuzz.2019.2921277

Abstract: This paper studies the problem of adaptive fuzzy dynamic surface control (DSC) of nonstrict-feedback nonlinear systems subject to unknown virtual control coefficients, dead zone, and full state constraints. The Nussbaum gain technique is used to… read more here.
