The design study was performed using finite element simulations. Numerical study shows that the obtained deflections vary from 77 to 462 μm for applied displacement ranging from 3 to 18 μm. Once the operating principle validated, a series of actuators has been machined and tested. Dynamic tests (unloaded) gives a maximum displacement about 230 μm for a frequency ranging up to 100 Hz. However the static tests give results with a good agreement with simulation. The developed actuators have been introduced into a demonstrator to show the feasibility of an intensification of heat exchange by electro-active morphing. The recovered data have demonstrated the feasibility of pumping for a traveling wave of 5 Hz closing quasi-totally the channel. Another result is the reduction of wall temperatures during the application of a traveling wave on the, thereby that the heat transfer was intensified. Moreover, an increase in the rate of flow was observed. All this results demonstrate the enhancement of heat transfer.","PeriodicalId":174767,"journal":{"name":"2013 IEEE 11th International Workshop of Electronics, Control, Measurement, Signals and their application to Mechatronics","volume":"274 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124256148","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}

A good realistic and real-time evaluation of electromagnetic activity of these circuits should help for EMC background and designing, but also should be convenient to optimize the electromagnetic behavior during the real activity of the electronics.","PeriodicalId":174767,"journal":{"name":"2013 IEEE 11th International Workshop of Electronics, Control, Measurement, Signals and their application to Mechatronics","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127953685","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}

Many control strategies have been proposed to fulfill the constraints of this connection, related mainly with the good distribution of the output current among the different legs. Model Predictive Control (MPC) is a recent control strategy that uses the system's model for predicting at each sampling instant, the future behavior of all the variables of the system. This paper presents a control strategy based in MPC with variable commutation instants for controlling two classical commutation cells connected in parallel. In order to reduce the impact of the time delay taken by the controller for executing the algorithm, a solution using the symmetry of the commutations in steady state is proposed.","PeriodicalId":174767,"journal":{"name":"2013 IEEE 11th International Workshop of Electronics, Control, Measurement, Signals and their application to Mechatronics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126498044","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 article however, describes two heuristic-global-optimization-based algorithms that not only require less computational time than DP, but also produce better solutions, with significantly lower fuel consumption cost.","PeriodicalId":174767,"journal":{"name":"2013 IEEE 11th International Workshop of Electronics, Control, Measurement, Signals and their application to Mechatronics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125774918","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}
