The goal is to control carefully the air flow to reduce emissions of pollutant particles and fuel consumption. First, T-S Fuzzy model is employed to represent the nonlinear system diesel engine. Secondly, based on T-S fuzzy model, a fuzzy observer design and H∞ controller design is proposed using a two-step approach to calculate the controller and the observer gains. Sufficient conditions are derived for asymptotic output tracking controllers in the format of Linear Matrix Inequalities (LMIs). Then, a single step approach is studied: the proposed approach considerably simplifies the design procedure and gives in only one step the controller and the observer gains. Both methods are applied to the system diesel engine. The effectiveness of the single approach is demonstrated through numerical simulation results.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116720639","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}

For this kind of systems the ability to self-reconfigure and adapt in response to changes in users requirements and environmental conditions is primordial. Several approaches have been proposed in the literature to achieve self-reconfiguration, however, as the complexity of the adaptive system grows, designing and managing the set of reconfiguration rules becomes difficult and error-prone. To tackle this limitation, we propose a new approach that uses a search-based evolutionary algorithm that explores valid configurations to find the most relevant one given a specific running context. Another salient advantage of our approach is the re-exploitation, in the context of adaptability, of the design knowledge and existing model-based technologies through the reuse of the feature model of the system.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114874524","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 general, catalytic ozonation processes operate with a deliberate ozone overproduction to obtain a treated water which respects the discharge standards. But, in this case, the oxygen consumption is not optimal and the operating costs are important. The objective of this study focuses on the optimization of the catalytic ozonation pilot. An optimal control is proposed to obtain a significant abatement of the pollutant. In this application, the pollutant abatement is represented by the absorbance.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127238803","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}

It consists in converting ambient energy into electricity to power and lengthen battery life. Dynamic voltage scaling (DVS) is one of the most effective techniques for reducing energy consumption in embedded and real-time systems. However, traditional DVS algorithms have inherent limitations on their capability in energy saving since they rarely take into account the actual application requirements and often exploit fixed timing constraints of the real-time tasks. Some authors used feedback scheduling techniques in order to minimize the consumed energy by observing the actual usage of resources in the system. This paper combines the use of DVS and energy harvesting with the capabilities of a feedback scheduler. Our goal is to minimize the consumed energy, as well as to take the charging model into account.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121012635","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 exploitation of such systems implies numerous operational challenges and one of them is to ensure people that they will be able to find a bike or to park it at each station. Therefore, the regulation system is necessary for maintaining a prefixed number of bikes at each station in order to fulfill at best the demand. In this paper, we develop a new stochastic Petri net model for control and performance evaluation of such transportation systems. Compared to our published works, in this paper, we consider a new rebalancing policy based on a real-time alert system with three levels of the stations control namely Ei (engorgement alert level), Pi (penury alert level) and Ri (desired level point).","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123277169","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}
