Sliding Mode Thau Observer for Actuator Fault Diagnosis of Quadcopter UAVs [PDF]
Applied Sciences, 2018 Fault diagnosis (FD) is one of the main roles of fault-tolerant control (FTC) systems. An FD should not only identify the presence of a fault, but also quantify its magnitude and location.

Robust Reduced Order Thau Observer With the Adaptive Fault Estimator for the Unmanned Air Vehicles [PDF]
IEEE Transactions on Vehicular Technology, 2023 Developing fault detection and diagnoses algorithms for the unmanned air vehicles such as the quadrotors is challenging since they are intrinsically non-linear, time-varying, unstable, and uncertain.

Modeling and Fault Detection of Quadrotor with Rotor Thrust Deviation Fault [PDF]
مجله مدل سازی در مهندسی, 2021 In this study, modeling and fault detection of a novel faulty quadrotor is presented. It is assumed that a quadrotor vehicle has encountered a fault during a flight accident, and as a result, one of the rotors does not operate vertically.

Phénomène d’Eaux Vertes à Picochlorum en lagune de Thau pendant les années 2018 et 2019. Observations environnementales [PDF]
, 2021 Après avoir été eutrophisée jusque dans les années 2000, la lagune de Thau est depuis sur une trajectoire de restauration écologique selon le processus d’oligotrophisation. Cependant, l’année 2018 est apparue comme une année de bascule dans son fonctionnement écologique par son contexte hydroclimatique perturbé avec l’apparition d’un phénomène inédit d’
