There are two indispensable methodologies for autonomous flights performed by unmanned
aerial vehicles (UAV). The first is flight control, and the other is simultaneous localization and …

In this survey, various concepts and methodologies developed over the past two decades for
varying and learning the impedance or admittance of robotic systems that physically interact …

This article proposes an unknown system dynamics estimator (USDE) based sliding mode
control for servo mechanisms with unknown dynamics and modeling uncertainties. An …

The accuracy is of great significance to the synchronization motion of the marine surface
vehicles (MSVs). However, the accuracy is highly affected by the uncertain hydrodynamic …

Limited computational resource is one of the features of the embedded system including
unmanned marine surface vehicle (MSV). Under this practical constraint, we aim to develop …

In this paper, the uncertainty and disturbance estimator (UDE)-based robust control is
applied to the control of a class of nonaffine nonlinear systems. This class of systems is very …

The uncertainty and disturbance estimation (UDE)-based robust control strategy is able to
achieve good robust performance by estimating and compensating the uncertainty and …

In this paper, the robust bipartite tracking consensus problem for second-order multi-agent
systems has been addressed in the presence of lumped disturbances and unknown velocity …

This paper presents the precision motion control of a piezoelectric nanopositioning stage
using a new scheme of adaptive sliding mode control with uncertainty and disturbance …

The control algorithm based on the uncertainty and disturbance estimator (UDE) is a robust
control strategy and has received wide attention in recent years. In this paper, the two …
