UAV is the acronym for Unmanned Aerial Vehicle. Currently, when browsing the Internet in search of related items, UAV is the most common term. This designation is used to define the flying object used for civil recreational and professional applications. Even if it seems that a common agreement has been reached online, aviation agencies in many countries have decided to opt for a different term than the current UAV. The UMS Skeldar V-200 is a medium-range UAV (unmanned aerial vehicle) VTOL (vertical takeoff and landing) developed by the Swedish aerospace company Saab.
The Skeldar can be used for surveillance, information gathering, light cargo transportation and electronic warfare. Since this is a rapidly growing market with numerous new opportunities every day, people involved in this burgeoning aeronautical sector are currently using several names to designate these unmanned aerial systems that are found in more and more areas. This study presents a comparative analysis of different configurations of unmanned aerial vehicles (UAVs) using a proposed universal UAV. The term unmanned aircraft system (UAS) emphasizes the importance of other elements beyond the aircraft itself.
However, the term drone mainly refers to an “unmanned aircraft” that is used primarily in a military context, while it is used to designate any type of unmanned aerial vehicle in common parlance. More precisely, the annex to the Missile Technology Control Regime equates rocket systems and unmanned aerial vehicles. This review focuses on three main challenges of controlling a quadrocopter unmanned aerial vehicle (UAV) as an underpowered mechanical system (UMS). A synthesis control method is proposed to control and monitor the position and attitude of the dynamic model of a small quadrorotor unmanned aerial vehicle (UAV), where the dynamic model is subactuated, highly coupled and is not linear.
Unmanned aerial vehicles are subject to complex aerodynamic or hydrodynamic forces and various uncertainties, making their dynamic modeling difficult. An unmanned aerial vehicle (UAV), commonly known as a drone, is an airplane without a human pilot on board. Nowadays, unmanned aerial vehicles (UAVs) have left the field of academic research and are becoming practical tools in a variety of applications, such as surveillance, rescue, remote inspection, reconnaissance, analysis of the atmosphere for prediction, aerial photography and sampling, etc. As the world pioneer in the creation and implementation of regulations for the use of commercial unmanned aerial vehicles, the French Civil Aviation Directorate (DGAC) refers to them as drones.
Research on the control of underactivated systems has been very active in the last decade due to the increase in the subactivation feature in a variety of applications, such as mobile robots and unmanned aerial vehicles (UAVs). The dynamics of unmanned aerial vehicles (UAVs), similar to most highly non-linear systems, have several characteristics that complicate the process of designing tracking or stabilizing the trajectory. Quadrotors are increasingly being used as the preferred platform for unmanned aerial vehicles (UAVs) for indoor applications.
