The photoanodes prepared with doctor blade were analyzed by X’pert Pro X-ray diffractometer to identify the anatase structure. The optical properties of the dyes and sensitized photoanodes in the region 400–800 nm were determined by UV–Vis spectrophotometer. The current-Voltage (I-V) characteristics of realized DSSCs were measured in AM1.5 solar irradiance spectra at ambient temperature using Keithley 6517A multimeter. The blocking layer leads to the enhancement of photoconversion efficiency (PCE) by physical separation of the substrate FTO and the electrolyte. There is a remarkable increase of Jsc which reaches 8.88 mA.cm$^{-2}$ compared to the cell without blocking layer, leading an efficiency of 3.9% under power radiation equal to 100mWcm$^{-2}$. The obtained results show a simple way to improve the performance of dye-sensitized solar cells based on TiO2","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133376734","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 SFOC strategy is penalized by its high sensitivity against parametric variations and particularly the stator resistance. This variation yields noticeable flux distortion, which affects considerably the system’s performance. Thus, SMFO is added to the control strategy of DFIM to ensure a robust control versus parameter variations. In such a way, sensors for speed and stator flux might be dismissed, to avoid cost increase and system reliability degradation. Simulation results on MATLAB/Simulink show that the proposed observer provides high-performance dynamic characteristics which shows the robustness of the proposed scheme against plant parameter variations.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115884135","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 dispositive is used essentially for the manufacture of titanium dioxide (TiO2) layers used as photo-anodes of dye sensitized solar cells (DSSCs). We present and discuss details of the electrical and control components. The voltage and the deposition time of the grown layers have been programmed using the LabVIEW software. The automation of the deposition system gives the possible regulation and more precise optimization than the manual use too and minimizes the error rate that can be caused by operator intervention. We had used this dispositive to prepare TiO2 films for different deposition voltages. We studied the effect of deposition voltage on the morphology structure of manufactured TiO2 layers and their thickness. We have noticed that the increase of the deposition voltage increases the thickness and causes an increase of the cracking through the TiO2 layer.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114717744","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 the first stage, an adaptive observer is designed to detect and estimate failures. The observer gains are determined by solving a Linear Matrix Inequality (LMI). Next, once the fault has been isolated and its size estimated, the fault can be accommodated by creating a new control into the faulty system. In this context, fault tolerant control systems are involved in automation engineering issues as a remedy to system reliability. Thereby, we interest in this work to the Pseudo Inverse Method (PIM) law to compensate actuator fault effects in order to guarantee desirable closed-loop performances. The system modeling and fault diagnosis are designed by a graphical concept, the bond graph tool as a useful methodology for multidisciplinary systems and which is based on causal and behavioral properties.

Therefore, the PSO algorithm has not only simplified the structure of RBF neural network, but also enhanced training speed and mapping accurate.
