Simulation and Implementation of a Modified ANFIS MPPT Technique
The maximum power point tracking (MPPT) algorithms ensure optimal operation of a photovoltaic (PV) system to extract the maximum PV power, regardless of the climatic conditions. This paper exposes the study, design, simulation and implementation of a modified advanced neural fuzzy inference system (ANFIS) MPPT algorithm based on fuzzy data for a PV system. The studied system includes a PV array, a DC/DC buck converter, the ANFIS controller, a proportional-integral (PI) controller, and a load. The simulation and experimental tests are carried out with the MATLAB/Simulink software and LabVIEW, respectively. Moreover, the obtained results are compared with previously published results by incremental conductance (IC) and fuzzy logic (FL) algorithms under different climatic conditions of irradiation and temperature. The results show that the proposed ANFIS algorithm is able to track the maximum power point for varying climatic conditions. Furthermore, the comparison analysis reveals that the PV system using ANFIS algorithm has more efficient and better dynamic response than FL and IC
Photovoltaic Power Control Using Fuzzy Logic and Fuzzy Logic Type 2 MPPT Algorithms and Buck Converter
This work presents the analysis, design, simulation and hardware implementation of the classical Fuzzy Logic (FL) and the proposed Fuzzy Logic Type 2 (FLT2) MPPT techniques for standalone PV System. FL and FLT2 MPPT algorithms are simulated via MATLAB/ Simulink and implemented via LabVIEW software and CompactRio hardware, in different climatic conditions. Also, they are compared to the Incremental Conductance (InC) MPPT algorithm, one of the most common used MPPT techniques. The studied system consists of PV array, DC/DC converter, MPPT controller, batteries and load. The PV array is connected to the DC / DC buck converter that works based on the output pulses of the MPPT controller to make the PV system operates at the Maximum Power Point (MPP). Thereafter, based on the simulations and the experimental results, a comparison is made to be useful for MPPT designers and researchers in this area
Design and Structure of an Electronic Switching System for Remote Circuits Structuring and Online Measurements
this paper presents design and structure of an electronic switching system for remote circuits structuring through internet, where the possibility of building circuits from scratch while conducting electrical measurements at any point of built circuits by online experimenters. This switching system enables to interconnect between electrical and electronic components in different combinations of circuits while providing an online environment highly approximated to physical environments of traditional hands-on laboratories in terms of manipulating measurement instruments and building experimental circuits. This paper also presents results of deployed topology for remote exploit of this switching system along with results of its deployed online engineering experiments
Design and Implementation of a Reservation System and a New Queuing for Remote Labs
Remote laboratories are important in education because they provide access to equipment that some institutions cannot afford to purchase or maintain, reduce the need for dedicated physical space for equipment and personnel to staff laboratories. But more than just fill the absence of real physical laboratories; remote laboratories can improve the users experience through the use of adaptive and specific. An important element in supporting shared access is coordinating the scheduling of the laboratory usage. Optimized scheduling can significantly decrease access waiting times and improve the utilization level of remote laboratories resources, with associated reductions in per-use costs.The user management systems that exist so far are limited, and not compatible with all remote lab interface development software. For that, we worked on the development of a new user management system for remote laboratories.This paper proposes a model and set of diagrams that define the new reservation system and a new Queuing for remote laboratories for educational purposes.</p
Online Laboratory in Digital Electronics Using NI ELVIS II+
This work is part of the ‘‘eSience’’ project, which is realized in the framework of Tempus project, coordinated by Bordeau university and financed by the European Union. The ‘‘eSience’’ project aims to create a network of online labs in the maghrebian countries.
The present paper will present our recent work in order to extend our online laboratory ‘‘Khouribga OnlineLab’’ at Hassan the 1 st university in Morocco. It will focus on the development of a digital online laboratory supporting experiments in the fields of combinational logic circuits, sequential electronics, and digital multiplexer. The developed system is combining NI ELVIS II+ and the NI digital Electronics FPGA board.
By using the interactive version of iLab Shared Architecture, students will have a complete access to manage and control the system in real time

Teaching Power Electronics and Digital Electronics using Personal Learning Environments. From Traditional Learning to Remote Experiential Learning
Practical works have a fundamental role in the curriculum of any scientist, engineer, and technician. It helps learners to face the real world and put in practice what they have learned to judge their operability. Moreover, due to some limiting factors and due to the growth number of learners, universities and institutes have become inapt to give efficient learning. Distance education presents a future key to reduce these restrictions. Currently, remote experiments together with web-based courses approach significantly contribute to many aspects of education for learners. In this context, the main question addressed is how we ensure that an educational system evolves to better serve the needs of learners? The present work proposes a solution based on student’s Personal Learning Environments ‘PLEs’. PLEs are educational platforms that help learners take control and manage their own learning process, learning modules with remote experiments, for reaching a specific goal. In order to response these criteria we use the Learning Management System (LMS) Moodle, the e-portfolio Mahara, the Remote Laboratory Management System (RLMS) iLab Shared Architecture (ISA) with additional tools and plug-ins to implement the learning by doing environment

Determination of the Synchronous Machine's Parameters Using the iLab Shared Architecture
The target of this work is to promote the experimental works via internet within the different laboratories of Hassan 1st University in Settat and our partners in eSiense group within the frame of Tempus project.
Tempus project aims to create a series of remote laboratories in Morocco, Tunisia and Algeria in cooperation with France, Austria, Romania and Greece and it is financed by the European Union.
In order to share knowledge, Morocco and these universities are working together in a collective work program in order to create leading laboratories, aiming to put into practice the experimental works in electrical engineering, that are accessible through internet. These experimental works tend to share the equipments existing in every University so as to make them possible for other universities to benefit from them.
This leading project will be generalized afterwards in order to engulf all the other fields, including different manipulations of measuring powers using electromechanical machines and measures concerning instruments.
This paper focuses on the implementation of the first remote laboratory in Hassan 1st University in morocco. It concerns the determination of the characteristics of the synchronous machine. For this, student accesses to our platform via internet to determine the parameters in Open Circuit characteristics OCC, Short circuit characteristics SCC and then the determination of the synchronous reactance Xs
