Item Induction motor condition monitoring using infrared thermography imaging and ensemble learning techniques(SAGE, 2021) Mahami, Amine; Rahmoune, Chemseddine; Bettahar, Toufik; Benazzouz, DjamelIn this paper, a novel noncontact and nonintrusive framework experimental method is used for the monitoring and the diagnosis of a three phase’s induction motor faults based on an infrared thermography technique (IRT). The basic structure of this work begins with this applying IRT to obtain a thermograph of the considered machine. Then, bag-of-visual-word (BoVW) is used to extract the fault features with Speeded-Up Robust Features (SURF) detector and descriptor from the IRT images. Finally, various faults patterns in the induction motor are automatically identified using an ensemble learning called Extremely Randomized Tree (ERT). The proposed method effectiveness is evaluated based on the experimental IRT images, and the diagnosis results show its capacity and that it can be considered as a powerful diagnostic tool with a high classification accuracy and stability compared to other previously used methods.Item Robustness Enhancement of Fractionalized Order Proportional Integral Controller for Speed Control of Indirect Field-Oriented Control Induction Motor(Wydawnictwo SIGMA-NOT, 2024) Ousaadi, Zahira; Akroum, Hamza; Idir, AbdelhakimThis article presents a novel approach for controlling an induction motor (IM) drive using a fractionalized order proportional integral (FrOPI) controller within an indirect field-oriented control (IFOC) scheme. In contrast to the conventional Integer Order PI controllers (IOPI), the FrOPI controllers demonstrate enhanced performance owing to their nonlinear characteristics and the inherent iso-damping property of fractional-order operators. The performance of the induction motor is thoroughly assessed under various conditions, including starting, running, speed reversal, and sudden changes in load torque. Simulation results are then presented to confirm the effectiveness of the induction motor drive when utilizing the FrOPI controllerItem Developing and implementing the performance of induction motors used in well pumping systems(2022) Belaroussi, Oussama; Terki, Amel; Ammar, Abdelkarim; Fedorovich, Kalinin VyaslavBecause water extraction from wells accounts for the bulk of energy consumption in irrigation operations globally, the sustainability and profitability of irrigation are strongly reliant on the energy efficiency of the pumping system. A technique that studies and improves the performance of motors used in well pumping systems is reported in this body of research as having been undertaken. In a similar manner, an experimental investigation of the energy efficiency of two modern systems of induction motor control has been carried out. According to the results, proper control performance is critical to achieving improvements in energy and efficiency. Using DTC-SVM for IM, the purpose of this study is to demonstrate a prototype of a pumping system that is powered by solar energy in the presence of changing radiation levels. Real-time MATLAB/Simulink simulations are used in conjunction with a dSpace 1104 board to carry out the hardware implementationItem Dynamic eccentricity fault diagnosis in induction motors using finite element method and experimental tests(Inderscience, 2017) Bouzida, Ahcene; Abdelli, Radia; Touhami, Omar; Aibeche, AbderrazakItem Performance of induction motor under the effect of voltage unbalance with loading consideration(Springer, 2015) Dekhandji, Fatma Zohra; Refoufi, LarbiItem Efficiency improvement in induction Motor-Driven solar water pumping system using golden section search algorithm(Springer, 2017) Djeriou, Salim; Kheldoun, Aissa; Mellit, AdelItem Efficiency improvement in induction Motor-Driven solar water pumping system using golden section search algorithm(Springer, 2017) Djeriou, Salim; Kheldoun, Aissa; Mellit, AdelItem Adaptive control of induction motor using artificial neural network with estimation of rotor flux(2007) Chetate, Boukhmis; Kabache, Nadir; Ladiguin, Anatoly NikolaevitchItem Feedback of the input voltage in FDTC control using a three-level NPC-VSI(2007) Zaimeddine, R.; Berkouk, E.M.A new control structure for sensorless induction machine dedicated to electrical drives using a three-level voltage source inverter VSI-NPC is completely analysed. The amplitude and the rotating velocity of the flux vector could be controlled freely. Both fast torque and optimal switching logic could be achieved; the selection is based on the value of the stator flux and the torque. A novel DTC scheme of induction motors is proposed in order to develop a suitable dynamic. We proposed a DTC approach based in fuzzy logic, in witch the response of torque and flux is enhanced trough optimal switching strategies and torque ripple minimisation is achieved. However, the middle point voltage of the input DC voltages of the three-level NPC voltage source inverter presented serious problems caused by a fluctuation of the DC voltage sources UCU, UCL. As consequence to these problems, we obtained an output voltage of the inverter, which is asymmetric and with an average value different from zero. We presented one solution to minimise this fluctuation. This solution used a feedback to regulate the input voltages of a three-level inverter VSI NPC. A scheme of a fuzzy direct torque control "FDTC" with complete cascade is simulated for an induction motor. The results obtained indicate superior performance over the FOC one without need to any mechanical sensorItem Two approaches for direct torque control using a three-level voltage source inverter with real time estimation of an induction motors stator resistance(2007) Zaimeddine, Rabah; Berkouk, EL Madjid; Refoufi, Larbi
