The constrained control of unmanned aerial vehicles (UAVs) is a challenging task due to
their nonlinear and underactuacted dynamics. This brief focuses on the position control of a …

Unmanned Aerial Vehicles have undergone rapid developments in recent decades. This
has made them very popular for various military and civilian applications allowing us to …

Abstract Unmanned Aircraft Systems (UAS) have seen unprecedented levels of growth
during the last two decades. Although many challenges still exist, one of the main UAS focus …

This article presents a novel adaptive controller for a small-size unmanned helicopter using
the reinforcement learning (RL) control methodology. The helicopter is subject to system …

This paper presents a novel sliding mode control (SMC) strategy based on approximate
feedback linearization and enhanced nonlinear disturbance observer for small-scale …

This paper presents a study on input-output feedback linearization control (OFLC) of a
laboratory twin rotor helicopter system based on an improved algebraic differential …

In this paper, the position and yaw angle trajectory tracking control problem is studied for
unmanned helicopters subject to both matched and mismatched disturbances. To achieve …

This article presents a control approach to obtain the better stabilization in attitude and
altitude of quad-rotor under different disturbance conditions. In the standard Quad-rotor rotor …

Attitude dynamic model of unmanned aerial vehicles (UAVs) is multi‐input multioutput
(MIMO), strong coupling, and nonlinear. Model uncertainties and external gust disturbances …

Aiming at the problem that how to design a controller without using model information for an
unmanned helicopter (UH), a novel data-driven method based on model free adaptive …
