However, they give rise to harmonic problems during the switching process. It impacts the total system performance.In this paper, Selective Harmonic Elimination SHEPWM was adopted to mitigate these undesirable harmonic distortions. It cancels odd harmonic at optimized switching angles. In this case, it aims to eliminate the first 100 low-order harmonics. The fsolve function was used to calculate the optimized 50 angles for the SHEPWM by solving the non-linear transcendental equations in MATLAB. The resulting SHEPWM is implemented in a low-cost high-performance PIC18F26K22 microcontroller. It controls a pure sine wave single-phase inverter in ISIS space. Finally, an LC low-pass filter is connected at the inverter output to ameliorate its response and obtain a better sinusoidal AC waveform with a lower THD.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"16 1","pages":"127-131"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82459629","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}

To deal with the stabilization problem, we employ the S-procedure lemma that generates four bilinear matrix inequalities (BMIs). By virtue of the matrix inversion lemma and the Schur complement, these obtained BMIs are therefore transformed into LMIs. The results obtained by the simulation show that the slave mechanical impact oscillator is well controlled and hence track the desired trajectory of the master.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"25 1","pages":"505-512"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90246207","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}

In our study, we tested the conventional theory (p-q theory) to detect the harmonics present in the electrical system.

These indicators should be chosen according to the company’s objectives, strategies, and key success factors. On the other hand, in a production system, KPIs are not independent and may have inherent interactions with each other. These interactions should be investigated and taken into account in the KPI selection process. The goal of this research is to present a decision support framework based on a Fuzzy Cognitive Map (FCM) for guiding decision-makers in the selection of KPI. The model is based on the idea that KPI may be assessed and chosen based on their impacts on the company’s strategic objectives. In addition, the model allows for the consideration of different causal interdependence between the KPI.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"24 1","pages":"97-102"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87205315","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 general nonlinear differential equation of the dynamics with a non-constant and nonlinear input matrix is considered.

Thus, by means of the obtained linear model, two different approaches for the design of the feedback gains of the affine PD controller are presented. At the end of this work, a two-degree-of-freedom manipulator robot is adopted to show the efficiency and then to compare between the two design approaches of the affine PD-based control law.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"3 1","pages":"424-432"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84055875","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}

If we refer to etymology, \"metrology\" means \"science of measurement\". The business measurement approach should therefore fall within the realm of rigor and rationality by performing periodic calibration. By using new technologies (IT, Machine learning, etc.), work methods can be innovated by modernizing measurement techniques and by introducing the notion of intelligence. \"SMART Metrology\" or \"intelligent metrology\" is therefore required to take care of the automatic calibration and monitoring of equipment and will provide reliable and repeatable measurements, which will be verified by legal metrology. It is therefore used to create SMART measuring instruments that transform measurement results into controlled information. More and more companies are opting for Smart metrology for the simple reason that it modernizes the techniques of taking measurements introducing new concepts, in particular Big Data. This technology offers metrologists the opportunity to develop their profession, allowing them to actively participate in the compliance of measuring instruments and the reliability of measurements in the company. This paper presents a SMART platform for calibrating spectrum analyzers available in a metrology laboratory using Python programming software. This Human Machine Interface (HMI) makes it possible to communicate in real time with the spectrum analyzers, to take measurements automatically, to supervise the instrument remotely in order to carry out the calibration and verification of the equipment and to judge the conformity of the equipment.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"68 1","pages":"193-197"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86668211","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}
