Thus, Maximum Power Point Tracking Controllers (MPPT) should be applied to achieve the maximum PV system power, irrespective of environment variations. The performance of these approaches differs in terms of energy recovery, conversion efficiency, response time and reliability, under various environmental conditions. This paper explores a comparative analysis between different MPPT, that are perturb-and-observe (P&O), incremental conductance (INC), and fuzzy logic controller (FLC). Using MATLAB / Simulink environment, a model of the PV module and the DC / DC boost converter was simulated using the various MPPT techniques. The simulation results demonstrated the advantage of the fuzzy controller at the operating point in terms of settling time, power loss, and oscillations compared with other techniques.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129812844","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}

This one has to improve power quality by compensation for harmonics of non-linear load in power distribution systems. The sliding mode control is among the effective techniques in transient and steady-state regimes. Usually, the sliding mode control uses hysteresis a regulator resulting in variable switching frequency, however, in this paper, this frequency is kept constant by modulating the output control signal. The nonlinear load harmonics and reactive power are identified using the well-known p-q theory. To measure the performances of the proposed control, a comparative analysis is given using conventional PI control. As expected, the obtained results, using simulation tests, have confirmed the performances of the sliding mode control, and its superiority to the conventional PI control.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128240450","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}

Parity space and observers approaches are used to generate residuals. To accomplish fault isolation, we use a bank of observers for all possible faulty models. The paper considers constant actuator faults, that is, the outputs of some actuators are stuck at fixed undesirable constant values. The fault isolation strategy is based on combining the conventional observer design techniques with adaptation techniques. Based on the designed observers, a bank of residuals are defined correspondingly. The actuator faults can be isolated if only one residual goes to zero while the others do not. The faulty model with residual approaching zero identifies the faulty actuators. For linear and nonlinear systems with all states available, new sufficient conditions for fault isolation are derived, which require only that the distribution matrices of the actuators are of full column rank.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"89 6 Pt 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129116032","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}

Characterized by inspiratory signals, it is closely related to the breathing function. This paper deals with the sleeping snore using an efficient approach based on the synthesis of a recorded snoring signal. The advantages of this approach are very varied such as offers of a non-contact substitute, artificial reproduction by machine of the original signal (snoring), which can even be integrated later in humanoid robots as an example. The method itself of this reconstitution is a reproduce of the signal through the application of some predictive techniques such as LPC (linear predictive coding), and CELP (Code-excited linear prediction). The difference between original and synthetic signals, called also residuals, can be explained by a scanning factor and different types of noises. Finally, to evaluate our approach, we compute the Segmental Signal to Noise Ratio (called segmental SNR which is a special SNR very useful for segmented signals.), and Root Mean Square Error (RMSE), both of which are suitable criteria for sound signals, decisive for us in order to show the effectiveness of these different methods.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121419587","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}
