An integral sliding surface is firstly constructed. Then, by using the Lyapunov-Krasovskii functional and some specified matrices, a sufficient condition is obtained in the form of linear matrix inequalities (LMIs) to ensure the sliding mode dynamics to be asymptotically stable. Furthermore, a sliding mode controller law is synthesized to guarantee that the system trajectories can be driven onto the specified sliding surface in a finite time and maintained there for all subsequent time. Finally, an inverted pendulum model is used to illustrate the advantages and effectiveness of the design method.","PeriodicalId":117908,"journal":{"name":"2017 International Conference on Engineering & MIS (ICEMIS)","volume":"159 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117181989","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 paper deals with the design of a PID controller in order to control a DC-DC boost converter in the PV system. For the design of the whole system, the used approach is based on the Energetic Macroscopic Representation (EMR). This technique goes from a complex command to a simpler one and is characterized by the use of cascading of one or more controllers. The three parameters of the controller are tuned by using Genetic Algorithm (GA). Both of the system responses using PID MPPT controller tuned by genetic algorithm and PID controller tuned by Pole Placement (PP) are tested when fast changing the solar irradiation is experienced. Finally, in order to obtain the best system performance, Perturb and Observe (P&O) MPPT method is applied to generate the output voltage reference Vref. The simulation results are compared in terms of mean squared error (MSE) criterion, percentage overshoot and rising time. The results show that parameters tuned by GA PID controller gives better performance.","PeriodicalId":117908,"journal":{"name":"2017 International Conference on Engineering & MIS (ICEMIS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117210549","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}

One of these is how to do a good job of tutoring students without face-to-face contact. This calls for the interpretation of large quantities of data generated as a result of the activities performed by students, which e-learning platforms collect and store. These data are also potentially very useful for preventing student dropout. We propose the use of knowledge discovery techniques to analyse historical student course grade data in order to be able to predict in real time whether or not a student will drop out of a course in the future. Logistic regression models are used for the purpose of classification. Experiments conducted with data on over 100 students for several real distance learning courses confirm the predictive power of our proposal that outperforms other existing approaches in terms of accuracy.","PeriodicalId":117908,"journal":{"name":"2017 International Conference on Engineering & MIS (ICEMIS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125407383","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 fact, in this paper we aim to solve the following issue: Given a control data flow graph a System on a Programmable Chip circuit; find a possible hardware-software partitioning of the graph on the System on a Programmable Chip in order to minimize the logic power and satisfying a temporal constraint.","PeriodicalId":117908,"journal":{"name":"2017 International Conference on Engineering & MIS (ICEMIS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126075992","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}

Several tasks which are treated as a multistage process construct the process of producing indexing information in continuous audio streams based on detected speakers. The main constructing blocks of such an indexing system contain components for an audio segmentation, speaker detection, speaker clustering, and speaker identification. In the proposed speaker-based audio indexing system, three probabilistic Linear Disciminant Analysis (PLDA) variants-standard, simplified and two-covariance-, and Gaussian Mixture Model (GMM) are proposed in the speaker identification stage. The evaluation is performed on audio data from the broadcast news domain and the obtained results demonstrate the superiority of two-covariance PLDA model in terms of performance results compared to other proposed algorithms.","PeriodicalId":117908,"journal":{"name":"2017 International Conference on Engineering & MIS (ICEMIS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125765998","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}
