Unmanned aerial vehicles (UAVs) are affordable these days. For that reason, there are
currently examples of the use of UAVs in recreational, professional and research …

This work presents a bond graph (BG) model and a robust cascaded controller for a twin-
rotor system (TRS). The BG model accounts for all the energetic and dynamical couplings …

In this paper, first, quadrotor dynamical equations are derived, and then, an auto-landing
algorithm is designed to land a quadrotor UAV on a specified location. A double-loop control …

The dynamic systems of unmanned aerial vehicles (UAVs) are susceptible to parametric
uncertainties, unmodeled dynamics, and external vibrational disturbances during motion …

Drones are important in precision agriculture applications since they represent a new tool
that can increase crop production. In this context, the digital processing of the images …

In this paper, a simultaneous calibration algorithm of the parameters of the attitude and
altitude control for an unmanned aerial vehicle (UAV) is proposed. The algorithm is based …

In this paper, the problems of chattering in sliding mode and high-accuracy flight tracking are
tackled. Indeed, a nonlinear controller for the position, altitude, and attitude tracking has …

This work introduces the Multi-Objective Particle Swarm Optimisation (MOPSO) algorithm to
optimise and speed up adjusting gains of a modified super-twisting second-order sliding …

In this paper, three sliding-mode-based control techniques for position and attitude tracking
trajectory for a quad-rotor unmanned aerial vehicle (UAV) are evaluated regarding the …
