It is mainly based on two signature generators: a fuzzy logic classifier and a based threshold conventional one. The two classifiers act on the available data by considering three thresholds which are made according to the generator PV typical parameters and with a total conformity with the standards. The proposed fault diagnosis approach requires only the available measured variables and is able to identify the most frequently met faults related to shading, temperature, leakage current and increased series resistance losses. The addressed PV generators are based on one diode model. The overall results have proved the proposed methodology capability in PV faults detection and identification.","PeriodicalId":6799,"journal":{"name":"2021 18th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"56 1","pages":"97-102"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81372101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thereby, sensors based on carbon nanotubes (CNT) materials are gaining importance due to their high flexibility, sensitivity and medical compatibility. Nanocomposite based strain sensors present an interesting potential of movements detection that helps to build the basis for body attached sensor networks, which have the capability for tracking finger movements, gestures and grasping. However, the output of the sensor is noisy and having outliers due to the random deformation of the CNT conductive paths during applied strain, which needs to be filtered. This paper presents S-TPU/C-TPU strain sensors attached to a glove for hand gesture recognition. A filtering study has been conducted of four digital filters for real-time processing of the recorded data (Moving average, Moving median, Savitzky-Golay, and Gaussian), which is required to improve the quality of the data for better gesture identification and classification. The filters are evaluated based on their real-time response and smoothing performance. The Savitzky-Golay filter was found to be the most suitable filter to remove the inherent noises and smooth the baseline and curves of the signal with a fast real-time response equal to 0.072s.","PeriodicalId":6799,"journal":{"name":"2021 18th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"5 1","pages":"1366-1371"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81987929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design of active and passive components is presented. The control circuit is based on the SRF algorithm for detecting the reference harmonic currents and on the phase-shifted carrier-based PWM technique for gating signals generation. Moreover, dimensioning of the SAPF input DC bus voltage and AC output current PI regulators are provided. The study is validated through computer simulations using MATLAB/Simulink.

In swarm robotics, there is not a well-structured methodology until today for developing robotic swarm systems. Several researchers have developed steps to design swarm robots but these steps are still incomplete. In this paper, we focus on the functional architecture of the swarm robots where we propose a top-down approach to ensure consistency and continuity from requirement level to behavioral level up to the functional and structural levels. This approach is based on the Model-Based Systems Engineering method (MBSE) using the Systems Modeling Language (SysML) where we present the allocations between the functions of each swarm member and the overall swarm behaviors. Then, we will be interested in the architecture of Robot Operating System (ROS) of a swarm behavior where we identify the allocations between the component and the functions of a robot.","PeriodicalId":6799,"journal":{"name":"2021 18th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"38 1","pages":"1438-1445"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82931572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach allows a reduced-complexity localization by minimizing the search space through multistage treatment. A neighbor discovery processing is first performed to identify the two nearest neighboring UEs among a set of UEs in the vicinity. The so selected neighbors are used as anchors (A-UE). Then, based on the signal strength, the distances separating the two A-UEs to the T-UE are determined. The distance estimates are used to plot two potential solutions of the Angle of Arrival (AoA) of T-UE. To distinguish the correct AoA estimate, oriented beamforming is performed around short arcs centered on the two AoA candidates. The user's position is then deduced based on the estimates of the AoA and the distance to the A-UEs. Our approach exploits the capabilities of neighbor discovery and oriented beamforming to provide an accurate position estimate for UEs experiencing harsh channel conditions that render direct localization at the base station difficult.","PeriodicalId":6799,"journal":{"name":"2021 18th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"44 1","pages":"503-509"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83949585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
