Scanning Electronic Microscopy (SEM) has been used in this investigated work to study the conduction process in XLPE insulation under thermal aging and different e-beam energies. The aged process is done under fixed high temperature equal to 140°C for 1500 h. The aged and fresh samples are subjected to the three levels of electron beam irradiation ranged from 5 keV to 30 keV. Our findings show that aging under high temperatures has a considerable effect on the conduction process of XLPE insulation. It is found that at the end of first 1000 h, the leakage current decreases and after all the aging time (1500 hours) the studied characteristic increases. The same behavior was observed when we have studied the effect of energy of applied irradiation. The falling of leakage current after 1000 hours of high temperature applying might be assigned to crystallinity increase. However, at the end of aging time (1500 hours), we have seen a rapid augmentation of leakage current caused by the augmentation of the conductivity of XLPE. In the other hand, the creation of outside imperfections caused by the aging process can contribute also in this increase.

This paper presents an implementation of an efficient direct flux and torque control for induction motor drive. In control design, the modeling inaccuracy and various uncertainties cannot be avoided when classical methods are conducted. Therefore, it is recommended apply the nonlinear-robust control approaches to cover these drawbacks. The sliding mode approach is proposed to achieve a decoupled control and improve its robustness versus different disturbances. Furthermore, an optimal control algorithm is joined for losses minimization and efficiency maximization. This technique consists of the computation of optimum flux reference according to the load value and improves the efficiency for no load or light loads state, that makes is very suitable for variable load applications. The effectiveness of the control techniques is verified using an experimental test bench based on dSpace 1104 real-time interface.

This article presents a comparative study in the AGC problem of interconnected power system with and without the presence of a High Voltage Direct Current (HVDC) Link. Simulations were carried out on three areas hydro-thermal power system composed by reheat thermal power plant in the first area and hydro power plants in the second and third area. For more realistic study, the effects of Generation Rate Constraint (GRC), and Governor Dead-Band (GDB) have been considered. Then, the Proportional Integral Derivative (PID) regulator is considered in all areas. The optimal controller settings are tuned using a powerful optimisation algorithm known as Grasshopper optimization Algorithm (GOA) by evaluating the Integral of the Squared Error (ISE). The dynamic responses with and without HVDC link were compared. The robustness of this system has been tested alongside Parametric Variations (PVs). From the obtained results, it is clearly observed the advantage of the HVDC link from different view of point such as: peak overshoots and under shoots, etc.

The aim of this paper is to accomplish the mobile robots full navigation by developing tools that are able to give a solution in faulty situations. It treats Simultaneous Localization and Mapping (SLAM) problem based on the Extended Kalman Filter (EKF) using proprioceptive and exteroceptive sensors affected by hardware faults. In this work, sensor Fault Detection and Isolation (FDI) approach using SLAM fusion is proposed which is based on a traditional method (duplication/comparison) when an absolute localization sensor is available. In order to gather accurate information about the FDI approach, mobile robot is equipped with a variety of sensors such as encoders, gyroscope, laser rangefinder and indoor GPS. The proposed approach was validated under realistic conditions using experimental data and good performances were obtained.

This paper presents the implementation of an experimental bench containing a single-phase grid-tie inverter with DC source using a Digital Signal Controller development board and a three-phase inverter shield. This is part of a study involving the prototyping of a complete photovoltaic systems. The study outlines indirect active and reactive power injection using a zero crossing detection (ZCD) method to master the synchronization of the generated voltage from the inverter and the power grid. The measurement board is used to gather the grid information such as phase shift and the amplitude of the grid voltage for the synchronization. The diagram shown in this paper describes the different parts of the experimental bench from the DC source to the grid line passing by different boards and components. The program is coded in C language and flashed to the Texas Instruments F28069M development board. The experimental results validate previous simulation results done using Matlab. This topic is part of a large study to achieve the laboratory’s strategy which aims to study and build micro power plants [1], [2] for the production of electrical energy based on wind and photovoltaic energy to response to the Algerian government plan in renewable energy.

nowadays, optimal control is an active research sub-area of control and systems engineering because of its applications in different human activities. Literature provides various algorithms for optimal control in various domains. At the same time the process is extremely computational exhaustive. For carrying out this task in real time a system which is really fast is required. Software does not seem to be a suitable candidate for implementing it in real time. We require some technology that has huge amount of parallelism. The high amount of computation power in limited time can be achieved by using FPGA as a platform. The proposed work of this paper is FPAG implementation using techniques of optimal command applied to a DC motor used in a physical pendulum, based on linear algebra and matrix calculation. The proposed implementation of our proposed observer is done using Xilinx System Generator (XSG) which co-simulated on both software/hardware using Simulink and XGS tools.

The restoration of images degraded by noise is one of the most important tasks in image processing. This paper deals with the recovery of an image from a Poisson noisy observations. More precisely, we have combined an iterative denoising algorithm based on Variance Stabilizing Transform (VST) with the conventional Wavelet Thresholding technique. At each iteration, a combination of the Poisson observations with the denoised estimate from the previous iteration is treated as scaled Poisson data and riltered through a VST scheme and wavelet thresholding. Experimental results show the effectiveness of the proposed method for denoising images corrupted by Poisson noise. Performance assessment is provided.

This work examines the assessment of wind energy capacity in the region of Annaba situated in Northeast of Algeria. The variation of the wind speed in terms of the altitude is required to evaluate the wind resources and predict the energy production of a given wind farm. Generally, the wind speed data, measured at a reference height, are extrapolated to the desired hub height using several empirical laws. In this paper, the power law method, suggested by Justus and Mikhail, is employed to extrapolate the Weibull parameters, using wind time series data obtained from the meteorological stations. Thus, the vertical extrapolated velocity is, then, used to evaluate the power and energy densities at heights of 30m and 60m. The obtained simulation results show that the considered site may be appropriate for small off-grid applications, but not for large wind turbines.

The aim of this work is to study the in phase (I) and quadrature (Q) imbalance problem in the receiver (RX) system. In this study, we use the characteristics of I and Q signals in time domain, which have the same amplitude and the phase between the two paths is 90 degrees to estimate the I and Q gain and phase imbalance components. Simulation results demonstrate that the proposed method can estimate the in phase and quadrature gain and phase mismatch parameters to compensate the receiver (RX) IQ imbalance problem.

Reducing the unwanted electrostatic charge to a safe level is the goal of any charge neutralization device. The aim of the present work is to study the influence of the voltage waveform and frequency on the efficiency of charge elimination by using a wire-to-grid dielectric barrier discharge (DBD). The DBD electrode was subjected to high voltages of various waveforms, amplitudes and frequencies. Three voltage waveforms, namely sinusoidal, square and triangular signals, were studied in neutralization of positively charged polyethylene (PE) granules. The resultant surface potential distribution, before and after neutralization, was measured using an electrostatic voltmeter. The obtained neutralization rates of the three voltage waveforms were compared in view to recommend the most efficient high voltage signal. The DBD currents, transferred charge and consumed power, corresponding to the three signals forms, were measured and compared. The obtained results show that the efficiency of the neutralization using the DBD electrode depends on both amplitude and frequency of applied voltage as well as the signal waveform. The square waveform was the more convenient signal leading to best neutralization results in comparison to the sinusoidal and triangular signals.
