The considerable increase in both the population growth of all types of industry is thought to find high quality technology to make drinking water. Two models can be used in this work: simple solar still and simple solar still coupled with heat pump. In this research, the productivity of water by SSD and SSDHP was determined by the orientation, the use of heat pump, the simple or double glass cover. The productivity can exceed 1.2L/m'h for the SSDHP and 0.5L/m'h for SSD model. The result of the global efficiency is determined for two models SSD and SSDHP gives respectively 30 %, 50 %. The internal efficiency attained 35% for SSD and 60 % of the SSDHP models. Convective heat coefficient can be determined is attained 2.5W/m2°C and 0.5 W/m2°C respectively for SSDHP and SSD models.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114518918","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}

These parameters are referred to as uncertainties. The modelling of uncertain systems is relevant in stability analysis methods such as Lyapunov theory. In addition, in robust control synthesis, the more information the model gives about uncertain parameter dynamics i.e. its value bounds and its variation rates, the best their performances are enhanced. Since the Linear Matrix Inequalities (LMI) approach has been introduced in the analysis and the control of complex systems, modelling parameter dependent systems is also relevant in the formulation and the resolution of LMIs. This paper is focused on the equivalence between Linear Parameter Varying (LPV) modelling of a Doubly Fed Induction Generator (DFIG) of a Wind Energy Conversion System use under both affine and polytopic structures. The stability analysis based on LMI approach is also carried out.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128256748","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}
