Active disturbance rejection control (ADRC) is a model-independent method widely used in
passive fault-tolerant control of the quadrotor unmanned aerial vehicle. While ADRC's …

UAVs are now applied to various fields, from military missions to civilian applications. A
malfunction in the drone's thrust system during flights can result in collisions and damages of …

The past decades have witnessed an increase in the use of multirotor unmanned aerial
vehicles (UAVs). This has led the way to the development of fault-tolerant control algorithms …

This paper studies a particular Unmanned Aerial Vehicle (UAV), called QBall 2+ quadcopter.
This vehicle is a complex system, non-linear, strongly coupled, and under-actuated. First, a …

Helicopter unmanned aerial vehicle (HUAV) are an ideal platform for academic researchs.
Abilities of this vehicle to take off and landing vertically while performing hover flight and …

In this paper, we propose the experimental validation of a fault observer which allows to
reconstruct the time behaviour of an injected fault effect on a quadrotor actuator. The …
