Aerial robotics is a very exciting research field dealing with a variety of subjects, including the attitude control. This paper deals with the control of a four rotor vertical take-off and landing (VTOL) Unmanned Aerial Vehicle. The paper presents a mathematical model based on the approach of Lagrange for the flight control of an autonomous quad-rotor. It, also, describes the controller architecture...
The present paper is intended for the detection and diagnosis of open-circuit faults in a three phase voltage inverter fed induction motor. Two techniques are being presented and used in order to achieve the open-circuit faults detection and localization. The paper concludes with a comparison between both these two techniques supported by some simulation and experimental results in order to illustrate...
The nonlinear loads generate harmonic currents which distorts the power quality in the distribution network, so it can be considered as a pollutant which pollutes the entire power system. To overcome problems due to harmonics, Shunt Active Power Filters are used as a solution. In this present work, Synchronous Reference Frame algorithm is selected to extract the harmonic components, Fuzzy Logic Controller...
In this paper we have synthesised the stability and robustness performance of MIMO compensator design for which the whole set of latent-structure can be assignment via the approaches of Block root placement technique. The purpose is to provide a comparative study between the Block pole structures in term of system response, and how can they affect the compensator structure meting a desired criteria.

In this paper, we propose a new intelligent sensor based on Electrolyte-Gated Graphene Field-Effect Transistor (EGG-FET) and Artificial Neural Network (ANN)-based Corrector, for high performance and low cost pH monitoring applications. The EGG-FET behavior is investigated analytically using an analytical drain current model based on drift-diffusion carrier transport which is given as function of chemical,...
The aim of this pro ect will be focused on creating two different types of flight controllers for the Airbus A320 using AT AB Simulink. The flight controller used for the aircraft has a decoupled flight controller and a coupled flight controller; a decoupled flight controller means the longitudinal stability derivatives and lateral stability derivatives will have their own state-space dynamic model,...
Bearing is one of the most critical components of rotating machinery. They are employed to support and rotate the shafts in rotating machinery. Therefore; any fault in the bearings can lead to losses on the level of production and equipments as well as the creation of an unsafe working environment for humans. For that reason, the bearing fault diagnosis has received considerable attention from the...
This paper presents a novel control scheme for unified power quality conditioner (UPQC) based on three-level neutral point clamped (NPC) inverter using fuzzy logic and Ann's for controlling respectively series and shunt APFs. The proposed UPQC is able to mitigate source current harmonics and compensate all voltage disturbances. It is designed by the integration of series and shunt active filters (AFs)...
In this paper, we propose a new strategy for Direct Torque Neural Network Control, compatible with a voltage inverter three level and exploit artificial intelligence tools namely: neural networks. In addition, the use of multi-level inverter and the artificial techniques contribute to improved performance of the control of the wind energy conversion system. In fact, the use of (multilevel converter)...
The detection and matching of point features play an important role in most of the computer vision algorithms, such as; for 3-D reconstruction and robotics navigation, localization and mapping. Over the last years various detectors and descriptors have been proposed and successfully applied to the different applications. However, the developed detectors are based on computationally intensive algorithms,...
In this article, we present the construction of observers of rotor flux and mechanical speed needed for robust control of the asynchronous machine. Two observers will be developed for comparison. The first is based on the technics MRAS and the second is observer of KUBOTA, with the enhanced DTC, “sensorless DTC”.
The growing interest in robotics has originated, in these recent years, the development of a high variety of intelligent and autonomous robots, and a great number of software frameworks for robotics. This paper surveys some representative of the existing of these development frameworks. In addition, it describes and compares their principal features and limitations. The paper provides also information...
The purpose of this paper is to apply a nonlinear control law for an unmanned quadrotor helicopter. First, the quadrotor dynamic model is established using Newton-Euler formalism and taking into account various physical phenomena that can influence its dynamic behavior. Subsequently, Backstepping controller is designed. Its job is to generate commands to the four rotors to drive the quadrotor to track...
