Motivated by the desire to extend the well‐known robust integral of the sign of the error
(RISE) feedback control to handle both matched and mismatched disturbances …

Parametric uncertainty associated with unmodeled disturbance always exist in physical
hydraulic systems, and complicate the advanced nonlinear controller design. In this paper …

This article presents a new adaptive parameter estimation method and the corresponding
control design for nonlinear servo mechanisms with friction compensation. A continuous …

An improved equivalent-input-disturbance (EID) approach is devised to enhance the
disturbance-rejection performance for a strictly proper plant with a state delay in a modified …

Increasing deployment of information technologies and low-inertia renewable energy
sources into smart grid fuel the uncertainties and reveal security and transient stability …

A tracking controller is developed for a class of uncertain nonlinear systems subject to
unknown time-varying input delay and additive disturbances. A novel filtered error signal is …

This paper presents a novel state-feedback control scheme for the tracking control of a class
of multi-input multioutput continuous-time nonlinear systems with unknown dynamics and …

A robust controller is developed for uncertain, second-order nonlinear systems subject to
simultaneous unknown, time-varying state delays and known, sufficiently small time-varying …

A robust tracking control method is presented in this paper for an uncertain plant with an
unknown state delay and an exogenous disturbance. The effects of the uncertainties, the …

A saturated controller is developed for a class of uncertain, second-order, nonlinear systems
which includes time-varying and nonlinearly parameterized functions with bounded …
