Two fuzzy controllers are proposed: the first one is dedicated to the maximum power point tracking (MPPT) of a variable speed permanent magnet synchronous generator wind turbine. The second fuzzy controller has the the objective to manage both the production and the storage of electricity for optimum performances of the system in respecting load demand. Several simulation results are given to show the effectiveness and the good performances of the proposed control structure.","PeriodicalId":403191,"journal":{"name":"EUSFLAT Conf.","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128804203","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}

Performance improvement analysis for resource allocation and motivation management is based on the marginal contributions of each elementary performance to the overall performance which give useful information on the way the overall performance has been achieved and would be improved.

The BCD model is proposed recently in order to analyse the intentional deviated users behaviour (prescribed behaviour crossing). This later is considered as a decision problem under risk where the consequences of users’ decisions can be evaluated following three attributes: the Benefit, the Cost and the Deficit. This paper proposes to consider the context of the decision, so we extend the BCD model by introducing different organizational and human factors that influence the users in their actions. This means that the deviation of users behaviour is not only related to their voluntary and intention but also to other factors, such as those of the organization of the system that has also some objectives to achieve as improving production and quality. To build the decision model based on the BCD approach, we propose a graphical representation using influence diagrams. The advantage of the proposed framework is to analyse the users’ decisions in terms of benefit or risk considering the context (as the organisational factors).","PeriodicalId":403191,"journal":{"name":"EUSFLAT Conf.","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134351117","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}

There are capable of keeping the combustion engine running within the optimal range in terms of fuel economy and performance. Power-split CVTs are a very specific type of CVT because this kind of transmissions are characterized by the combination of a traditional mechanical transmission and a continuously-variable transmission. A CVT powersplit design for high-power vehicles combines the advantages of pure hydrostatic drives at low speeds with the high eciency of power split drives at higher speeds. In this paper, a general control-oriented modeling approach based on Takagi-Sugeno (T-S) fuzzy models for the design of fuzzy observers for sensor-fault detection in power-split continuously CVTs is developed. It has been shown by simulation studies and experimental results that this approach can be used to reconstruct a selection of measurable values such as the hydrostatic pressure under varying load conditions and switched transmission modes.","PeriodicalId":403191,"journal":{"name":"EUSFLAT Conf.","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134333975","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}
