Motion control theory applied to multi-rotor aerial vehicles (MAVs) has gained attention with
the recent increase in the processing power of computers, which are now able to perform the …

This paper presents an overview on the state of the art in copter drones and their
components. It starts by providing an introduction to unmanned aerial vehicles in general …

A novel proportional-integral-derivative (PID)-type motion controller for a quadrotor is
introduced in this paper. A rigorous analysis of the closed-loop system trajectories is …

Detection of leaks of fugitive greenhouse gases (GHGs) from landfills and natural gas
infrastructure is critical for not only their safe operation but also for protecting the …

The aim of this article is to design and verify various control techniques for a quadrotor using
a quaternion representation of the attitude. All attitude controllers use a quaternion error to …

There exists an increasing demand for a flexible and computationally efficient controller for
micro aerial vehicles (MAVs) due to a high degree of environmental perturbations. In this …

A nonlinear robust and adaptive backstep** control strategy is hierarchically proposed to
solve the trajectory tracking problem of hexacopter UAVs. Due to the under-actuated and …

Accurate trajectory tracking is a critical property of unmanned aerial vehicles (UAVs) due to
system nonlinearities, under-actuated properties and constraints. Specifically, the use of …

The sole means for conventional multirotor UAVs to achieve horizontal translation motion is
by inducing changes in vehicle attitude. The lack of horizontal force control not only …

This paper proposes a methodology to detect metals using a drone equipped with a metal
detector and programmed by machine learning (ML) models. Our proposed research …
